Raypak 155C Maintenance and Care Procedures, Basic Tips if Heater will not Fire

Page 7

SECTION 3 / MAINTENANCE AND CARE PROCEDURES

To be followed one month after start-up and then semi-annually.

1.Inspect top of heater and draft hood for soot, (a sticky black substance around finned tubes and "V" baffles), and open flue gas passageways.

CAUTION: Soot may be combustible. Wet sooted surfaces completely prior to cleaning. Do not use steel wire brush.

2.Clean main burners and pilot burner of dust and lint.

3.Inspect and operate all controls, gas valve and pressure relief valve.

4.Make a visual check of the burner and pilot flame. Flame pattern on the main burner and pilot is indicated in the previous illustration. Yellow flame means restriction of the air openings. Lifting or blowing flame indicates high gas pressure. Low flame means low gas pressure. Should this occur, shut the heater off and contact your gas supplier or qualified service agency.

5.On indoor heaters, clean room intake open- ings to assure adequate flow of combustion and ventilation air.

CAUTION: Combustion air must not be contaminated by corrosive chemical fumes which can damage the heater and void the warranty.

6.Keep area around heater clear and free from combustible materials, gasoline and other flammable and corrosive vapors and liquids.

BASIC TIPS IF HEATER WILL NOT FIRE:

1.If you have no electrical power; it may be your "circuit breakers" have tripped. Try re-setting them.

2.If you have electrical power but the heater will not fire

check the following:

3.The time clock must be moved to the "ON" position.

4.Your pump strainer basket may be full. If so remove debris.

5.Your filter may be dirty. If so, backwash or clean filter. (To tell if your filter is dirty, the gauge pressure will be higher than usual).

6.The pump may have lost it's prime. It may be running dry, check the pressure gauge on the filter. If there is no pressure; then you are not moving water (or your gauge is broken). Try to get the pump to run at it's normal flow rate.

POOL & SPA WATER CHEMISTRY

Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water pH between 7.4 and 7.8 and total alkalinity between 100 and 150 p.p.m. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and also damaging the heater. If the pH drops below 7.2, the heater will be severely dam- aged. This will result in corrosion of the heat ex- changer. Heat exchanger damage resulting from chemical imbalance is not covered by the warranty.

AUTOMATIC CHLORINATORS AND CHEMICAL FEEDERS

All chemicals must be introduced and completely diluted into the pool or spa water before being circu- lated through the heater. Do not place chlorine tablets or bromine sticks in the skimmer. High chemical concentrations will result when the pump is not running (i.e. overnight).

Chlorinators must feed downstream of the heater and have an anti-siphoning device to prevent chemical back-up into the heater when the pump is shut off.

NOTE: High chemical concentrates from feeders and chlorinators that are out of adjustment will cause very rapid corrosion to the heat exchanger in the heaters. Such damage is not covered under the warranty.
