To light the SU-3 Gas Burner

1. Set the thermostat to the lowest

temperature

2. The control knob on the gas

valve should be in the "OFF"

position for at least five minutes.

3. Rotate the control knob counter-

clockwise to the "ON" position

and set the thermostat to the

desired temperature settings

Before turning the burner on, check for gas supply leaks. Check the wiring diagrams; install

manometers before and after the gas valve. Keep the observation port of the boiler or furnace

open. Follow the instructions on the nameplate of the burner to turn it on. Follow the sequence of

operations for the control (see pages 8 and 9). Record the readings below.

BURNER OPERATION: Record the Readings at Steady State

Draft over fire at steady state (should be –0.02 "W.C. or zero)

Natural Gas CO

% = (9.0% to 9.8%) or O

Stack Temperature (300

Percentage of Carbon Monoxide (CO) in PPM

Incoming Gas/LP pressure = "W.C. (minimum 5")

Natural Gas manifold gas pressure = "W.C. (3.5" required + - 0.3")

Carbon Monoxide in flue ( less than 100 PPM ideal; should not exceed 400PPM)

Maintenance Instructions

Once a year, a qualified service agency needs to be contracted for other than routine maintenance.

The blower motor is the only moving part. It does not require lubrication, since the ball bearings have

been permanently lubricated.

The user should do periodic visual checks of the burner and the flame.

Laundry lint or dog and/or cat hairs should not go inside the blower. If they are seen, they should be

removed after disconnecting the power to the burner and cover parts should be installed before starting the

burner.

Keep the area around the conversion burner clear and free from combustible materials, gasoline, and

other flammable vapors and liquids.

5. No obstruction for the flow of combustion and ventilating air (ref. Page 4).
