Replace any parts showing wear.

c. Check pump coupler for wear and vibration.

7. Check flow switch paddle.

8. Clean room air intake openings to ensure ade-

quate flow of combustion and ventilation air.

9. Keep boiler area clear and free from combustible

materials, gasoline, and other flammable vapors

and liquids.

*Should be checked monthly. (Takes approximately

15 minutes).

LOW NOX BOILERS

—

Models 181 to 401

The boilers are certified and tested under the latest

edition of the ANSI Z21.13 standards for hot water

boilers.

The boiler should be installed to meet the latest edition

of all local codes, the National Fuel Gas Code Z223.1

and the National Electrical Code, ANSI/NFPA 70.

CAUTION:

Combustion air must not be

contaminated by corrosive chemical fumes which

can damage the boiler and void the warranty.

DETAIL A

Fig. 44: Burner Detail

Operation

On call for heat, the ignition system, consisting of an

electronic spark module, and gas pilot system is ener-

gized. Providing pilot is proven, blower will start

running, the main gas valve will open and the boiler

will operate. When the operating control is satisfied the

boiler will shut down.

Start-Up (S8600H)

1. Turn on power to the boiler with gas supply off.

2. Check ignition module as follows:

a. Set the thermostat or controller to call for heat.

b. Watch for continuous spark at the pilot burner.

c. Check the ignition spark operation. Time must

be within the lockout timing period (90 sec-

onds).

d. Turn control down to end call for heat and wait

60 seconds before beginning step 3.

3. Turn on gas supply.

4. Set controller to call for heat.

5. System should start as follows:

a. Spark will turn on and pilot gas valve will open.

b. Main valve and blower will be powered after

pilot flame signal is proven.

c. Heater will operate until call for heat is satis-

fied.

Blower Adjustment

The blower is set for optimal operation. If adjustment is

needed, see Fig. 46.

Visual Inspection

Flame can be observed through the slot opening

above the plenum. Flame color is blue and evenly

spread on the top surface of the burner. At least every

three months a visual inspection should be made of

the burners. In case flame lifting is observed, check

gas pressure on manifold and static pressure in

plenum. Gas pressure in manifold should be 3.9" W.C.

and static pressure in plenum should be greater than

0.5" W.C.

Electrical

Be sure that electrical service to the boiler has proper

overload fuse or circuit breaker protection and wire
