For Model 200N (for use with natural gas)

Piping must be clean and free from scale or burrs.

Install regulator supplied with heater. Connect with 1/2”

NPT nipple (not included) to Control Valve.

Connect the appliance to an appropriately designed and installed fuel supply system. This system must include an approved manual shut-off valve which is readily accessible and is located within six (6) feet of the appliance.

Additionally, a sediment trap or drip leg must be located upstream of this manual shut-off valve. Refer to the appropriate (natural gas) installation code noted above. If a flexible connector is used, it must be of an approved type.

Before attempting to ignite the appliance, all gas fittings and connections must be thoroughly checked for gas leaks. Apply a small amount of a mild soap and water solution to all fittings and connections and observe for escaping bubbles. If any leaks are detected, shut off the gas supply to the appliance immediately. Wait a minimum of five minutes, repair the leak(s) and retest for leakage. Dry all fittings and connections after leak testing.

LIGHTING AND SHUT DOWN

Lighting the Heater

1 Before attempting the light the heater, smell all around the heater area for gas. Be sure to smell next to the floor because LP Gas is heavier than air and will settle on the floor. Turn on the gas supply to the appliance and check all fittings and connections for gas leaks using a mild soap and water solution. NEVER use a

match to check for gas leaks. Should a gas leak occur, shut off the gas supply to the appliance immediately. Wait a minimum of five minutes before repairing the leak.

2 Use only the fuel intended for this appliance. Check the appliance rating plate for the correct fuel information.

3 Turn the gas valve knob clockwise to the “OFF” position. See Fig. 1 and Fig. 2 for location of appliance parts.

4 Wait a sufficient length of time (at least five minutes) to allow gas which may have accumulated in burner compartment to escape.

5 Turn on the main gas supply.

6 Turn the gas valve knob counter-clockwise to the

“PILOT” position (see Fig. 1).

7a Depress and turn Control Knob counterclockwise to

“Pilot” position and hold for 1-2 minutes. This may take longer to purge air from the supply hose depending on the length of the hose being used.

Depress red spark ignition button to light pilot flame

(repeat until pilot lights) and continue to hold Control

Knob at “Pilot” positionfor 30-60 seconds to enable

Pilot Light Safety System.

Fully turn Control Knob to “Hi” position to light burner. or...

7b To light the pilot, move the lighting hole cover aside

(see Fig. 1) and place a lighted match into the hole.

Depress the gas valve knob and hold while lighting and observing the pilot burner. Ensure that the pilot burner ignites from the match. Allow the pilot to burn approximately 30 seconds before releasing the gas valve knob. If pilot does not remain lighted, repeat the lighting operation allowing a longer period of time before releasing the gas valve knob.

NOTE: In cases where long runs of gas supply lines have been installed ahead of the appliance, it may be necessary to bleed trapped air out of the supply lines before lighting the pilot. New installations generally require bleed of supply lines. Wait a minimum of five minutes after bleeding the supply lines before attempting to light the heater.

Adjust pilot if necessary as noted under “Pilot Burner

Adjustment.”

DO NOT operate this heater if any part has been under

water. Call a qualified service technician to inspect the appliance and to replace any part of the control system or gas control valve which has been under water.
