GAS SUPPLY AND PIPING

DIRECT/STANDARDINLETPIPING

WARNING

EDGES OF SHEET METAL HOLES MAY BE SHARP. USE GLOVES AS A PRECAUTION WHEN REMOVING HOLE PLUGS.

When gas piping enters directly to the gas valve through the stan- dard inlet hole, the installer must supply straight pipe with a ground joint union to reach the exterior of the furnace. The rigid pipe must be long enough to reach the outside of the cabinet to seal the grommet cabinet penetration. A semi-rigid connector to the gas piping can be used outside the cabinet per local codes.

INDIRECT/ALTERNATEINLETPIPING

When gas piping enters indirectly to the gas valve through the alternate gas inlet hole the following fittings (starting from the gas valve) to reach the outside of the cabinet must be supplied:

•Coupling.

•90 degree elbow.

•2 inch close nipple.

•90 degree elbow.

•Straight pipe, with a ground joint union, to reach the exterior of the furnace. The rigid pipe must be long enough to reach the outside of the cabinet so as to seal the grommet cabinet penetration. A semi-rigid connector to the gas piping can be used outside the cabinet per local codes.

GAS PIPING CHECKS

Before placing unit in operation, leak test the unit and gas connec- tions.

WARNING

TO AVOID THE POSSIBILITY OF EXPLOSION OR FIRE, NEVER USE A MATCH OR OPEN FLAME TO TEST FOR LEAKS.

Check for leaks using an approved chloride-free soap and water solution, an electronic combustible gas detector, or other approved testing methods.

NOTE: Never exceed specified pressures for testing. Higher pressure may damage the gas valve and cause subsequent overfiring, resulting in heat exchanger failure.

Disconnect this unit and shutoff valve from the gas supply piping system before pressure testing the supply piping system with pressures in excess of 1/2 psig (3.48 kPa).

Isolate this unit from the gas supply piping system by closing its external manual gas shutoff valve before pressure testing supply piping system with test pressures equal to or less than 1/2 psig (3.48 kPA).

PROPANEGASTANKSANDPIPING

WARNING

IF THE GAS FURNACE IS INSTALLED IN A BASEMENT, AN EXCAVATED AREA OR CONFINED SPACE, IT IS STRONGLY RECOMMENDED TO CONTACT A PROPANE SUPPLIER TO INSTALL A GAS DETECTING WARNING DEVICE IN CASE OF A GAS LEAK.

•SINCE PROPANE GAS IS HEAVIER THAN AIR, ANY LEAKING GAS CAN SETTLE IN ANY LOW AREAS OR CONFINED SPACES.

•PROPANE GAS ODORANT MAY FADE, MAKING THE GAS UNDETECTABLE EXCEPT WITH A WARNING DEVICE.

A gas detecting warning system is the only reliable way to detect a propane gas leak. Rust can reduce the level of odorant in pro- pane gas. Do not rely on your sense of smell. Contact a local propane gas supplier about installing a gas detecting warning sys- tem. If the presence of gas is suspected, follow the instructions listed in the Safety Precautions section of this manual.

All propane gas equipment must conform to the safety standards of the National Board of Fire Underwriters, NBFU Manual 58.

For satisfactory operation, propane gas pressure must be 11 inch WC at the furnace manifold with all gas appliances in operation. Maintaining proper gas pressure depends on three main factors:

1.Vaporization rate, depending on temperature of the liquid, and “wetted surface” area of the container or containers.

2.Proper pressure regulation. (Two-stage regulation is recommended for both cost and efficiency).

3.Pressure drop in lines between regulators, and between second stage regulator and the appliance. Pipe size will depend on length of pipe run and total load of all appliances.

Complete information regarding tank sizing for vaporization, rec- ommended regulator settings, and pipe sizing is available from most regulator manufacturers and propane gas suppliers.

Since propane gas will quickly dissolve white lead and most stan- dard commercial compounds, special pipe dope must be used. Shellac-based compounds resistant to the actions of liquefied pe- troleum gases such as Gasolac®, Stalactic®, Clyde’s® or John Crane® are satisfactory.

Refer to the following illustration for typical propane gas installa- tions and piping.
