Program Overview

In this scenario, participants will focus on inspecting multiple types of Gas Appliances in order to determine if they are safe to be lit or not.

Core Learning Objectives

Inspecting and defining the status of the key categories of each Appliance present inside the experience area, such as:

  • Venting 
  • Combustion Scoring
  • Piping
  • Documentation
  • Work Completion
  • AOC Recognition
  • Proper Documentation after all inspections are accomplished
  • Documentation
  • Overall Score (combination of all other learning objectives shown as passed/failed)

Tools

  • Laser Pointer — to interact with menus and objects in this experience, aim your laser pointer at an interactable item and pull the controller's trigger to select it.

  • Voltage Pen — to inspect a meter for electric current, place the pen tip near the meter to detect if it is electrified. If present, the tip will light up red and beep.

  • Matches — to conduct a Flame Test, move the matches near the appliances’ draft hood component and pull the controller's trigger.

    • If smoke moves towards draft hood — the test has passed

    • If smoke moves away from draft hood — the test has failed

  • Thermometer — to conduct a thermometer test, make sure that the gas valve is turned on. The thermometer will then start filling with a red color from the bottom to the top:

    • If red color fills up to 70 or 80 percent full — the test has passed

    • If thermometer does not fill up — the test has failed

 

Instructor Mode

After logging in, Trainers can use the "Add Scenario" screen in the Lobby to build a specific scenario. You can select:

 

  • Which Basement the User Enters (Basements 1-4)

    • Basement 1 — Has Furnace, No Boiler
    • Basement 2 — Has Boiler, No Furnace
    • Basement 3 — Chance for Multiple Furnaces and Water Heaters
    • Basement 4 — Chance for Multiple Boilers and Water Heaters

  • Missing or Disconnected Appliances (present / not present)

  • Universal Items

    • Pipe Capped / Uncapped

    • Water Present / Not Present in Sink

    • Vent Present / Not Present

  • Water Heater

    • Model Type (Atmospheric, Power Vented, Tankless, Electric)

    • Select 0-3 Defects

  • Furnace

    • Model Type (Atmospheric, High Efficiency)

    • Select 0-3 Defects

  • Dryer

    • Model Type (Top Lint Trap, Front Lint Trap (gas), Front Lint Trap (electric), Dual Unit)

    • Select 0-2 Defects

  • Oven / Range

    • Model Type (Pilot Light, White Electric Ignition, Black Electric Ignition)

    • Select 0-2 Defects

  • AOC Probability (Select 0-3)

How to Get 100%

There are four different basements that can appear within the module. If Instructor Mode is not in use, these will appear randomly.

 

The difference between basements:

  • Basement 1 — Has Furnace, No Boiler
  • Basement 2 — Has Boiler, No Furnace
  • Basement 3 — Chance for Multiple Furnaces + Water Heaters
  • Basement 4 — Chance for Multiple Boilers + Water Heaters

General Walkthrough

  1. Read and Close Work Order.

  2. First, before checking any Appliances, make sure that the sink has water.

    1. If a sink does not have water, all water-using gas appliances (water heaters and boilers) cannot be lit and must be tagged out.

  3. Check for AOCs.

    1. If any AOCs are found, select them using the laser pointer.

    2. Select “Have Customer Remove”

    3. Select “Issue Advisory Hazard Tag”

    4. List of Possible AOCs:

      • Gas or Kerosene Containers

      • Flammable Liquids

      • Dead Animals

      • Painting or Staining

      • Lawnmower

      • Pile of Old Clothes

      • Piles of Rags

      • Boxes

  4. Check for Uncapped Pipes. These are present when an Appliance is missing from the basement.

    1. Select the pipe to see if it is capped or not.

    2. If it isn't capped, cap it.

  5. Inspect Appliances for Defects

  6. Perform the Appliance Lighting Test:

    1. Turn on the Gas Valve. If the Gas Valve is missing, report it as “Appliance was Not Lit, Issued Hazard Tag”.

    2. Next, turn on the unit. Select the appliance’s component (gas control valve, burners, oven control, pilot light holes) to open the menu.

    3. A yellow or blue flame will appear.

      • If the flame is blue and there are no defects — select “Appliance Lit, No Hazards Identified”

      • If the flame is blue but there are warning type defects — select “Appliance Lit, Issued Advisory Hazard Tag”

      • If the flame is blue but there tag out type defects — select “Appliance was Not Lit, Issued Hazard Tag”

      • If the flame is yellow — select “Appliance was Not Lit, Issued Hazard Tag”

    4. For Ranges, there are further tests:

      1. Turn on all burners by using the burner control (circle switch)

        • If the flame is blue and if there no defects — select "Appliance Lit, No Hazards Identified"

        • If the flame is yellow — select “Appliance was Not Lit, Issued Hazard Tag“ in the appliance's menu

      2. For Pilot Light Ranges:

        1. Turn on gas, then open the range’s top.

        2. Find the gas regulator and select it in order to light the unit.

          • If the flame is blue — continue the inspection and start testing the burners

          • If the flame is yellow — select “Appliance was Not Lit, Issued Hazard Tag“

            • If the user tested burners before performing Light Unit test — they will fail the combustion category for this appliance

            • If the user tries to perform a thermometer test after the yellow flame icon appears — they will fail the combustion category for this appliance

            • If the user started the thermometer test before performing the appliance lighting test — they will fail the combustion category for this appliance

    5. For Dryers with a Pilot Light:

      1. Turn on the gas, then turn on the dryer.

      2. Select the small hole on the front part of the dryer. Then light the unit.

        • If the flame is blue — select “Appliance Lit, No Hazards Identified”

        • If the flame is yellow — select “Appliance was Not Lit, Issued Hazard Tag”

  7. Perform a Flame Test: (applies to boilers, water heaters, and central heating units/furnaces)

    • Note: The match test is applicable to atmospheric appliances only.

    1. Open Wrist Menu > Toolbox, then select the Match tool.

    2. Move to the appliance’s draft hood and select it.

    3. Observe the smoke which is emitting from the match:

      • If smoke moves towards the draft hood — the test has passed

      • If smoke moves away from the draft hood — the test has failed

        1. Select “Appliance was Not Lit, Issued Hazard Tag” in the appliance’s menu.

      • Additionally, the draft hood’s menu will say if the match test passed or failed. It will clearly state “Match Test: Passed” or “Match Test: Failed” after the test is performed.

  8. Perform a Thermometer Test: (applies to ranges and dryers)

    1. Turn on the Gas Valve:

      • If the appliance is a pilot light type — turn on by selecting it with the laser pointer.

      • If the appliance is not pilot light type — turn on by selecting the button or knob on the control panel.

      • Dryers Only — the thermometer is located inside of the dryer so the door must be opened first.

    2. Check Flame Color:

      • If the flame was blue — proceed to the next step

      • If the flame was yellow — proceed with the thermometer test

    3. When the thermometer first appears it is empty. It will then start filling with a red color from the bottom to the top. 

      • If the thermometer fills up — the test has passed

      • If the thermometer stays empty — the test has failed

        1. If it fails, select “Appliance was Not Lit, Issued Hazard Tag“ in the appliance's menu.

  9. Diagnose the Problem.

    1. Once all Appliances are lit or shut down, open the Wrist Menu (located on left wrist) and select “Communication”

    2. Choose the most accurate diagnosis in the window based on their inspection:

      • Appliances Lit — No Hazards Identified

        • Select if no issues occurred and all appliances were lit (with blue flame)

      • Appliances Lit — Hazards Identified

        • Select if some issues occurred and all appliances were lit (with blue flame)

      • Hazards Identified and Disconnected Appliances

        • Select if some issues occurred and NOT all appliances were lit (with blue flame)

  10. Experience Ends.
