Construction Heaters

Installation (Continued)

4.Open natural gas supply valve slowly.

5.Check all connections for leaks.

Never use an open flame to check for

a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak that must be corrected. Correct all leaks at once.

6. Close natural gas supply valve.

Operation

Review and understand the

warnings in the General Safety Infor- mation section. They are needed to safely operate this heater. Follow all local codes when using this heater.

TO START HEATER

1.Follow all installation, ventilation, and safety information.

2.Locate heater on stable and level surface. Make sure strong drafts do not blow on heater.

3.Make sure unit is turned off by lightly depressing and turning control knob fully clockwise to OFF.

4.Open gas supply valve on gas supply slowly.

NOTE: If not opened slowly, excess-flow check valve on propane tank may stop gas flow. If this happens, you may hear a click inside the regulator assembly. This is the check valve closing. To reset the excess flow check valve, close propane supply valve and open it again slowly.

5.Slightly depress and turn control knob counterclockwise to the low position (See Figure 6 or 7).

6.With the control knob pushed all the way in, press and release the piezo ignitor button. Keep pressing ignitor button until the burner lights. Hold control knob down for a maximum of 15 seconds while attempting ignition. If heater does not ignite, release control knob and wait 3 minutes before attempting reignition.

NOTE: Keep hands and face away from outlet (around top of shell) of heater while attempting to start heater.

7.After ignition, hold control knob down for approximately 30 seconds. This activates the automatic control system.

8.When burner remains lit, set heater at the desired heat level by slightly depressing the control knob and turning counterclockwise to the Medium or High settings (See Figure 6 or 7).

9.If burner goes out, turn off gas. Slightly depress and turn control knob fully clockwise to OFF. For propane model, check for adequate fuel supply. Restart heater beginning at Step #1.

Running heater below specified

input rating may cause flashback. During flashback, the burner flame is mostly yellow. The flame will burn inside the burner tube, causing a roaring noise. If flashback occurs, turn heater off. After burner tube cools, restart the heater.
