Horizontal Thru-wall Venting System (Category IV) Installation

This installation utilize the boiler mounted blower to vent the combustion products to the outdoors. Combustion air is taken from inside the room and the vent is installed horizontally through the wall to the out- doors. Adequate combustion and ventilation air must be supplied to the boiler room in accordance with the National Fuel Gas Code or, in Canada, the latest edi- tion of CSA B149 Installation Code for Gas Burning Appliances and Equipment.

UL 1738 Certified Venting Material (e.g. AL29-4C) MUST be used. The vent must be installed to prevent flue gas leakage. Care must be taken during assembly to ensure that all joints are sealed properly and are air- tight.

For certain installations, i.e. pool, heat pump, domes- tic hot water supply with pre-heat tank, PVC or CPVC may be used. Contact manufacturer for details.

To prevent condensate accumulation in the vent, it is required to install the horizontal portion of vent with a slight upward slope of not more than 1/4" per foot of horizontal run and an approved condensate trap must be installed per applicable codes, so the condensation in the vent pipe drains back to the boiler.

WARNING: For common vent installations contact factory.

WARNING: No substitutions of flue pipe or vent cap material are allowed. Such substitutions would jeopardize the safety and health of inhabitants.

The Stainless Steel non-restrictive direct vent cap must be furnished by the boiler manufacturer in accordance with its listing.
