INSTALLATION
2.1.
To facilitate installation, locate machine near gas, air and
electrical outlets. Place unit approximately one foot from
wall and level machine with spirit level.
2.1.1.
Connect gas supply to 3/4" pipe connection
located at rear of machine. When connecting to natural
gas, use pipe size large enough to permit 4" of water
column operating pressure. If machine is to be operated
on bottled gas, use a regulator on the gas tank and operate
on water column pressure of 11". Connect air to air blow
gun on right side of unit. 3/8" copper tubing can be used
with appropriate fittings.
NOTE :
This machine is equipped with a gas pressure gauge
located on front at control section. This pressure
gauge indicates burner operating pressure and is
calibrated to read pressure in inches of water column.
Operating gas pressure is set by adjusting shut-off
petcock located in burner compartment.
Check and comply with local municipal safety codes
when making installation.
2.1.2.
After completing gas connections, check for leaks by using
soap bubble test applied with a soapy brush on all fittings
while system is under pressure.
2.1.3.
Plug in power cord to 115 volt outlet. The power cord is
provided with a third wire for grounding the cabinet in
accordance with standard safety practices.

INSTALLATION CHECKOUT (Refer to Exploded View Drawing)
3.1.
Light burner pilot light. Make sure Timer is in OFF position, and
blower is stopped. Open gas shut-off cock. Turn pilot valve setting
on Basoid Valve to highest position and hold down red plunger stem.
Light pilot light and continue to hold down red plunger for at least
60 seconds while pilot light is burning. This heats the safety
thermocouple which controls main gas supply to burner.
3.2.
Light burner by turning on timer. Burner should light, blower motor
should run and gas pressure gauge should indicate operating pressure.
Check pressure gauge to make sure pressures are within operating safety
ranges. Use 4" for natural gas and 11" for bottled.
3.3.
If pressure exceeds these limits, adjust pressure by rotating shut-
off gas cock until proper pressure is obtained.
