ADDENDA: LOW NOx HEATERS Models 181 to 401

The Raytherm Low NOx Heater is offered with WH1- On-Off firing (standard) or 2-stage firing (optional).

The heaters are certified and tested under the latest edition of the ANSI Z21.10.3/CSA 4.3 standard for hot water heaters.

The heater should be installed to meet all local codes, the National Fuel Gas Code ANSI Z223.1, and the National Electrical Code, ANSI/NFPA 70-latest edition.

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 and the blower will begin running.

b. Heater will operate until call for heat is satisfied.

BURNER ADJUSTMENT

This burner assembly does not require any primary air adjustments.

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. A visual inspection should be made monthly of the burners. In case flame lifting is observed on the burner, check gas pressure on manifold and static pressure in plenum. Gas pressure in manifold should be 3.9" WC and static pressure in plenum should be greater than 0.5" WC

OPERATION

On call for heat, the ignition system, consisting of an electronic spark module, gas pilot system is energized. Providing pilot is proven, blower will start running, the main gas valve will open and the heater will operate. When the operating control is satisfied, the heater will shut down.

ELECTRICAL

Be sure that electrical service to the heater has proper overload fuse or circuit breaker protection, and wire size and connections comply with all applicable codes.

HIGH GAS PRESSURE SWITCH

Pressure switch senses high pressure and automati- cally shuts down burner if abnormal pressure exists.

START-UP PROCEDURES

(S8610B Ignition Module)

1.Turn on power to the heater 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 (15 or 90 seconds). d. Turn control down to end call for heat and wait 60 seconds on lockout models before beginning step
