20 MAINTENANCE

PERIODIC QUICK CLEANING

We recommend that you periodically brush the outside of the burner slots with a brass wire brush and clean the burner tube through the combustion air vent with the tool we have provided.

This can be done by locating the burner combustion air vent (1) underneath the bowl bracket and inserting the tool through each combustion air vent, rotating the tool. Be

careful when inserting the burner cleaning tool not to damage the igniter electrode.

mCaution: It is important to increase the frequency of this cleaning procedure during the spring and summer months.

Ignition System

If the Ignition System fails to ignite the burner, light manually. If Manual ignition is suc- cessful, then check the Ignition System.

Check that both the white (2) and black (3) ignition wires are attached properly.

Check that the igniter button pushes in completely and returns.

Check to see if the igniter is loose in the frame. Tighten if necessary; see Step

“Install Igniter” (Pg.11, Step 9B) for the correct procedure.

If the Ignition System still fails to ignite the burner, use the Manual Lighting procedure and contact your dealer.

Burner Flame Pattern

The burner has been factory set for the correct air and gas mixture. The correct flame pattern should have yellowish tips (4) dark blue in the middle (5), and light blue at the burner tube (6). If the flames do not appear as shown, or if “popping” noises occur, fol- low the burner cleaning procedures.
