3. Use wrought iron or steel pipe for all gas lines. Pipe dope
should be applied sparingly to male threads only.
CAUTION: If flexible stainless steel tubing is allowed by the
authority having jurisdiction, wrought iron or steel
pipe must be installed at the gas valve and extend a
minimum of two (2) inches outside of the unit casing.
pipe must be installed at the gas valve and extend a
minimum of two (2) inches outside of the unit casing.
WARNING: Natural gas may contain some propane. Propane,
being an excellent solvent, will quickly dissolve
white lead or most standard commercial com-
pounds. Therefore, a special pipe dope must be
applied when wrought iron or steel pipe is used.
Shellac base compounds such as Gaskolac or Sta-
lastic, and compounds such as Rectorseal #5,
Clyde's or John Crane may be used.

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

5. The gas supply should be a separate line and installed in ac-
cordance with all safety codes as prescribed under “Limita-
tions”. 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.

FLUE VENT HOOD
The flue vent hood with screen is not shipped attached. This hood
must be installed to assure proper unit operation. The hood must
be fastened to the outside of the side gas control/electrical com-
partment with the screws provided in the bag attached to the in-
side of the gas control/electrical compartment, see Figure 3.

CAUTION
The flue exhaust hood must be properly installed and within the
recommended clearances. Further communications and action
must be given to the home or building owner(s) to eleiminate
any unauthorized humon contact around this area during the
heating cycle. Flue hood surface and immediate area is de-
signed to operate at high temperatures during the heating cycle.
