PREVENTIVE MAINTENANCE
Spiders, mud wasps, and other insects can build nests in burner tube. This causes poor combustion,
delayed ignition or ignition outside combustion tube. Listen for a change in burner sounds or in
flame appearance from a hard blue flame to a soft lazy flame or one that is very yellow. These are
indications of an obstruction in the burner tube (Fig. 6-3C). Inspect and clean on a regular basis.
a. Remove air shutter screw (Fig. 6-3B) and slide air shutter (Fig. 6-3A) down burner tube.
b. Rub a flexible wire brush down burner tube (Fig. 6-3C) until it is visible at end of burner
tube.
c. Vacuum burner where it enters combustion tube.
d. Return air shutter to original position and replace screw.
HOW TO CLEAN PILOT MODELS
1. Checkmain burner orifice and pilot assembly for contamination (dirt, spider webs, etc.).
2. Clean main burner tube with small brush.
3. Main burner adjustment - open air shutter 1/4 way.
4. Low pilot flame. Checkfor contamination - if clean have the pilot orifice replaced.
HOW TO CLEAN ELECTRONIC IGNITION MODEL
1. Checkmain burner orifice.
2. Clean and adjust main burner.
3. Main burner and valve manifold must align with each other.
4. Checkelectrode for cracked porcelain.
5. Checkelectrode for proper gap - 1/8” between electrode and ground.
6. If module board functions intermittently, remove board and clean terminal blockwith pencil
eraser.
WATER HEATER TANK CARE
I
CAUTION: Turn off water heater and allow time for water to cool before removing drain
plug to flush tank.
WINTERIZING (FLUSHING) INSTRUCTIONS
1. Turn off your main water supply - pump or water hook-up source.
2. Drain the water heater inner tank. Due to the location of the drain plug, approximately two
quarts of water will remain in the bottom of the tank. This water contains most of the
harmful corrosive particles. While draining the unit, if water flows sporadically or trickles
instead of flowing steadily, we recommend one of two things. First open the relief valve to
allow air into the tank and secondly, take a small gauge wire or coat hanger device and poke
through drain opening to eliminate any obstructions.
3. After thoroughly draining tank, flush with air pressure or fresh water.
• IF YOU USE AIR PRESSURE, it may be applied through the inlet or outlet valve on the
rear of the tank. It may also be applied through pressure temperature relief valve, but first
remove pressure temperature relief valve support flange. With drain valve open, air
pressure will force the remaining water along with corrosive particles out of unit.
• IF YOU USE FRESH WATER, it may be pumped into tankwith the assistance of an
onboard pump or external water through the inlet or outlet found on rear of tank. It may
also be applied through pressure temperature relief valve support located on front of unit.
Continue this flushing process for approximately five minutes to allow ample time for
fresh water to agitate stagnant water on bottom of tankand force deposits through drain
opening.
