GAS CONNECTION

The gas supply line can be routed within the space and roof curb, exiting through the unit’s basepan. Refer to Figure 8 for the gas piping inlet location. Typical supply piping arrange- ments are shown in Figures 20 and 21. All pipe nipples, fit- tings, and the gas cock are field supplied or may be purchased in UPG accessory kit #1GP0404.

Gas piping recommendations:

1.A drip leg and a ground joint union must be installed in the gas piping.

2.Where required by local codes, a manual shut-off valve must be installed outside of the unit.

3.Use wrought iron or steel pipe for all gas lines. Pipe dope should be applied sparingly to male threads only.

Natural gas may contain some propane. Propane is an excellent solvent and will quickly dissolve white lead and most standard commercial compounds. A special pipe dope must be used when assembling wrought iron or steel pipe. Shellac based com- pounds such as Gaskolac or Stalastic, and com- pounds such as Rectorseal #5, Clydes’s or John Crane may be used.

4.All piping should be cleaned of dirt and scale by ham- mering on the outside of the pipe and blowing out loose particles. Before initial start-up, be sure that all gas lines external to the unit have been purged of air.

5.The gas supply should be a separate line and installed in accordance with all safety codes as prescribed under “Limitations”.

6.A 1/8-inch NPT plugged tapping, accessible for test gage connection, must be installed immediately upstream of the gas supply connection to the unit.

7.After the gas connections have been completed, open the main shut-off valve admitting normal gas pressure to the mains. Check all joints for leaks with soap solution or other material suitable for the purpose. NEVER USE A FLAME.

FIRE OR EXPLOSION HAZARD

Failure to follow the safety warning exactly could result in serious injury, death or property damage.

Never test for gas leaks with an open flame. use a commercially available soap solution made specifi- cally for the detection of leaks to check all connec- tions. A fire or explosion may result causing property damage, personal injury or loss of life.

The furnace and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing at pressures in excess of 1/2 PSIG.

Pressures greater than 1/2 PSIG will cause gas valve damage resulting in a hazardous condition. If it is subjected to a pressure greater than 1/2 PSIG, the gas valve must be replaced.

The furnace must be isolated from the gas supply piping system by closing its individual manual shut- off valve during any pressure testing of the gas sup- ply piping system at test pressures equal to or less than 1/2 PSIG.

LP UNITS, TANKS AND PIPING

All gas heat units are shipped from the factory equipped for natural gas use only. The unit may be converted in the field for use with LP gas with accessory kit model number 1NP0441.

All LP gas equipment must conform to the safety standards of the National Fire Protection Association.

For satisfactory operation, LP gas pressure must be 10.5 inch W.C. at the unit under full load. Maintaining proper gas pressure depends on three main factors:

1.The vaporization rate which depends on the temperature of the liquid and the “wetted surface” area of the con- tainer(s).
