Cleaning the Combustion Chamber and
Flame-trap
1. Follow procedure outlined in “Removing the Burner
Door Assembly”.
2. Use a vacuum cleaner/shop vac to remove all loose
debris in the combustion chamber (Figure 30A). Use
compressed air to clear any dust or debris that may
have accumulated in the flame-trap.
3. Reassemble following the procedure under “Replacing
the Burner Door Assembly”.
Replacing the Burner Door Assembly
result in death, explosion, or fire.
WARNING
Replace manifold component block if missing
or removed.
Replace door gasket if damaged.
Failure to follow these instructions can
Replace viewport if glass is missing or
damaged.
Tighten both burner door screws
securely.
Explosion Hazard
Remove any fiberglass between gasket
and combustion chamber.
1. Check the door gasket for damage or imbedded debris
prior to installation.
2. Inspect the viewport for damage and replace as required.
3. Insert the burner assembly into the burner
compartment, making sure that the burner assembly
sits firmly against the burner bracket inside the
combustion chamber (Figure 30B).
IMPORTANT:
Do not scrape or nick the wires during
installation.
4. Inspect the door gasket and make sure there is no
fiberglass insulation between the gasket and the
combustion chamber.
5. Replace the two screws which secure the burner
assembly to the combustion chamber and tighten
securely. There should be no space between the
gasket part of the burner door and combustion
chamber. IMPORTANT: Do not operate the water heater
if the door gasket does not create a seal between the
burner door and the combustion chamber.
