Re-installing Inner Door/Manifold/Burner Assembly
Insert the manifold/burner assembly in the
burner chamber compartment, making sure
that the tip of burner manifold tab engages in
the proper slot of the bracket (see Figure 8).
Important:
•
The tip end of the burner manifold MUST be placed
in the
upper
slotted portion for models with input rate
of 40,000 to 50,000 Btu/hr to obtain proper installation.
• The tip end of the burner manifold MUST be
placed in the
lower
slotted portion for models with
input rate of 60,000 to 75,000 Btu/hr to obtain proper
installation.
After con
fi
rming no materials of any type are between
door gasket and combustion chamber shield, align
the screws on the inner door with the screw holes
on the combustion chamber and tighten with 1/4”
nutdriver or 1/4” socket & ratchet (see Figure 7). After
tightening the inner door screws, visually inspect
area around door gasket and skirt for spaces or
gaps. The door gasket MUST be sealed completely
in order for the water heater to perform properly.
DO NOT OPERATE THE WATER HEATER IF THE
DOOR GASKET DOES NOT CREATE A SEAL
BETWEEN MANIFOLD DOOR AND COMBUSTION
CHAMBER.
Reconnect the manifold tube to the gas control valve/
thermostat (
Note:
Do Not apply any thread sealant
at this connection). To prevent any cross threading
the manifold tube should be started by hand (turn
clockwise for natural gas, counter-clockwise for L.P.).
Upon tightening with the
fi
ngers and con
fi
rming it has
not been cross threaded, tighten nut with a 3/4” open
end wrench (see Figure 7).
Reinstall the insulation pad which was removed in
step 7 above.
Reconnect all the electrical connections to the bottom
of the gas control valve/thermostat, gently pushing
each connector up until it snaps into place (see Figures
7 & 10).
Reconnect the electrical power to the water heater in
the wall outlet and turn the main gas supply back “ON”
to the gas control valve/thermostat.
Restart the water heater by following the directions on
the “Lighting and Operating Instructions” label located
on the front of the water heater. Test gas connections
by brushing on an approved non-corrosive leak
detection solution. (
Note:
Do not splash the solution
on control. If a leak is detected, shut the water heater
down by following the directions on the “Lighting and
Operating Instructions”. Repair the leak(s) and repeat
this step.
Upon verifying proper operation of the water heater,
replace the insulation and outer door.
