DRAFT HOOD
MATCH
After successfully lighting the water heater, allow the unit to
operate for 15 minutes and check the draft hood relief
opening for proper draft (Figure 17). Make sure all other
appliances in the area are operating and all doors are closed
when performing the draft test. Pass a match flame around
the relief opening of the draft hood. A steady flame drawn
into the opening indicates proper draft.
FIGURE 17.
If the flame flutters or is blown out, combustion products are
escaping from the relief opening. If this occurs, do not operate
the water heater until proper adjustments or repairs are made
to the vent pipe system and/or air supply requirements.
