Venting

CAUTION: Proper installation of flue venting is criti- cal for the safe and efficient operation of the heater.

General

Flue Exhaust Tee

An optional Flue Exhaust Tee is available to facilitate horizontal venting. Any reference to horizontal venting that exits the back of the heater requires this tee. Refer to Table J for the appropriate kit for your model.

Table J: Flue Exhaust Tee Kits

Appliance Categories

Heaters are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent.

Category I – A heater which operates with a non-pos- itive vent static pressure and with a vent gas temperature that avoids excessive condensate pro- duction in the vent.

Category II – A heater which operates with a non-pos- itive vent static pressure and with a vent gas temperature that may cause excessive condensate production in the vent.

Category III – A heater which operates with a positive vent pressure and with a vent gas temperature that avoids excessive condensate production in the vent.

Category IV – A heater which operates with a positive vent pressure and with a vent gas temperature that may cause excessive condensate production in the vent.

See Table K for appliance category requirements.

NOTE: For additional information on appliance categorization, see appropriate ANSI Z21 Standard and the NFGC (U.S.), or B149 (Canada), or applicable provisions of local building codes.

CAUTION: When condensate traps are installed, condensate must be routed to an appropriate container for neutralization before disposal, as required by local codes.

WARNING: Contact the manufacturer of the vent material if there is any question about the appliance categorization and suitability of a vent material for application on a Category III or IV vent system. Using improper venting materials can result in personal injury, death or property damage.

Support of Vent Stack

The weight of the vent stack or chimney must not rest on the heater vent connection. Support must be pro- vided in compliance with applicable codes. The vent should also be installed to maintain proper clearances from combustible materials.

NOTE: During winter months check the vent cap and make sure no blockage occurs from build-up of snow or ice.

Barometric Damper

A barometric damper may be required when vent heights exceed 25 feet or when the draft is greater than -0.08 in. WC. In these installations, a barometric damper (single or double acting) is recommended.

The damper should be installed NO CLOSER than 18 in. from the discharge of the unit and no closer than 18 in. from a combustible ceiling. The damper can be installed in horizontal or vertical runs of vent pipe as necessary. Installation in a bull-head tee is acceptable as shown in the NFGC.

The weights on the damper should be adjusted per the damper manufacturer’s instructions for proper opera- tion.
