All installations and services must be performed by qualified service personnel.
: The vent and air intake elbows must be kept away from bushes, shrubs or any
vegetation that may restrict the flow of flue products. It must also be kept clear of any leaves,
weeds or other combustible materials. Keep the vent hood clear of snow. Avoid locating the
terminals in areas where standing water or condensate drippage may be a problem.
VENT TERMINAL LOCATION GUIDELINES
In addition to following the requirements outlined by local codes, utilizing the guidelines below when
possible in locating the vent terminal will help insure the trouble-free operation of your horizontally vented
furnace:
•
Avoid locating the vent terminal on a wall facing the prevailing winds and wide open areas.
•
When this is not practical, choose locations that protect the vent from strong winds such as behind a
fence or hedge. NOTICE: The vent terminal must be located a sufficient distance from bushes,
shrubs, and vegetation so as not to have the flue products restricted or blocked from such vegetation.
•
In areas with considerable snowfall, it is advisable to locate the vent terminal higher than the minimum
12 in. above the ground as to prevent blockage by snow accumulation or drifting.
Measures should be taken to prevent the entry of corrosive chemicals or vapors to the combustion and
ventilation air supply. Such chemicals include but are not limited to chlorinated and/or fluorinated
hydrocarbons such as found in refrigerants, aerosol propellants, dry cleaning fluids, degreasers and
removers. Other harmful compounds may come from bleaches, air fresheners or mastics. Vapors from
such products can form acid compounds when burned in a gas flame. The life of the furnace could be
reduced should acid compounds form within your furnace.
NOTICE: Heat exchanger failure caused from contaminated air will void its limited lifetime warranty.
NOTICE: The vent termination and air inlet elbow shall be checked periodically, at least at the start of
each heating season, for restriction or blockage from foreign material in the vent pipe or in the air inlet.
The air inlet and vent pipe should be cleaned when necessary.
E1. SINGLE PIPE (SIDEWALL) VENTING OPTION
This furnace may be horizontally vented with a single exhaust pipe. This will be a non-direct vent
installation. The same exhaust venting guidelines apply except the exhaust termination will be similar to
the air intake of the "2 pipe" direct vent installation. Refer to intake terminal instructions Figure 3 and
Figure 5. Termination will consist of one 90° elbow pointed downward. (See figure 2)
