Burner installation
Attaching the burner to the heat exchanger lid
1. Place the heat exchanger lid on a flat surface.
2. Position the burner gasket on the lid, aligning it with the screw holes.
3. Install the new burner in place:
a. Use the three M4 x 6 mm screws to secure the burner and gasket onto the new heat exchanger
lid.
b. Tighten the screws gradually by hand, plus an additional one-eighth (⅛) turn in a cross pattern.
Do not over-tighten.
4. Inspect the refractory for cracks, degradation and flatness. If in doubt, replace with a new one. (See
warning above regarding the refractory).
5. Carefully insert the refractory into the heat exchanger combustion chamber, using the alignment marks
for proper positioning.
6. Ensure that the orange heat exchanger lid gasket is in good condition, flat, and free of debris.
Reinstalling the burner and heat exchanger lid assembly
1. Carefully insert the lid-burner assembly straight down, ensuring that:
There is limited contact between the burner and refractory
The markings made previously on the lid, lid gasket, heat exchanger, and refractory are aligned.
2. Attach the heat exchanger lid and burner assembly onto the new heat exchanger with the six hex nuts
and perform the following:
a. Tighten nuts by hand in a cross pattern, similar to how the burner was tightened
b. Tighten an extra ½ to 1 turn.
Caution
Over-tightening will warp the heat exchanger lid and lid gasket, allowing fumes or
flames to leak.
3. Re-install the ignitor:
a. Position the ignitor gasket on the heat exchanger lid, aligning it with the screw holes.
b. Carefully insert the ignitor into the heat exchanger assembly by sliding it straight down.
c. Tighten the two #2 Phillips screws screws by hand, then an extra ⅛ turn.
4. Reconnect the following cables:
The ignitor cable
The gas valve cable
The two electrical connectors to the fan.
