Connect the Supply Gas Line

A manual shut off valve (gas cock), 1/8 in. plugged test port and 6 in. drip leg must be installed prior to the gas train. The valve and the test port must be accessible for the connection of a test gauge. Supply gas connections must be made by a qualified installer and are not furnished by manufacturer.

Test the System for Leaks

Check both the supply lines and the factory piping for leaks. Apply a soap and water solution to all piping and watch for bubbling which indicates a leak.

warning

NEVER test for a gas leak with an open flame.

Note

The factory piping has been checked for leaks, but should be rechecked due to shipping and installation.

Installation of Building Pressure Control (optional)

Mount Pressure Tap

Using the factory provided bracket, mount the pressure tap to the outside of the

unit. Choose a location out of the prevailing winds and away from supply or exhaust fans to assure accurate readings.

Run Pressure Tap Lines

Run a pressure tap line from the pressure tap on the outside of the unit to the low pressure tap on the back of the photohelic gauge. Run a second pressure tap line from the high pressure tap on the back of the photohelic gauge to the space. Fifty feet of tubing is supplied with the unit.

Set the Building Pressure

The pressure gauge is used to set the desired building pressure. The pressure is set by adjusting the knobs for the upper and lower pressure limits. Typical settings are

0.0in. wg for the lower and 0.10 in. wg for the upper pressure setting.
