Table 7A. Elevations up to 2000 Ft.
Table 7B. Elevations from 2000 Ft. to 7,700 Ft.
1. Determine termination type and pipe size.
2. Determine number of elbows in exhaust pipe. Do not include the
elbows in the termination or the condensate trap. Corresponding
number in Table 7 indicates the maximum length of exhaust pipe.
3. Determine number of elbows in inlet pipe. Do not include the
elbows in the termination. The corresponding number in Table 7
indicates the maximum length of inlet pipe.
NOTE: Use Table 7A at elevations up to 2000 ft (610 m) and use
Table 7B at elevations from 2000 ft (610 m) to 7,700 ft (2,347 m).
IMPORTANT: Do not use vent elbows in this vent pipe installation.

INTEGRATED FILTER INSTALLATION
The air intake filter included with the unit must be installed
according to the installation instructions supplied with the lter.
Installation steps are shown in Figures 13-16.
When installing the adaptor rubber boot, note the following:
• Remove and dis c ard the plast ic c ap f rom the outer cla m shell
housing. See Figure 13.
• To connect heater to the air inlet, use the vent adaptor
rubber boot provided in the base skirt. The adaptor rubber
boot is designed for 3” venting (Figure 14).
NOTE: if there is a need for 2” venting, then use plastic pipe
ttings to transition down.
• Loosen the hose clamp at the adaptor rubber boot and slide
the plastic piping into the adaptor rubber boot. With piping in
place, tighten the hose clamp. Install a 3” x 3” x 2” drain/waste/
vent tting to trap airborne particulates. See Figure 15.
NOTE: If piping has been previously cut with a saw, be sure to
remove all burrs and plastic shavings from the piping before installing.
NOTE: The heater must never be operated without the lter
media installed.
