These models have built-in drafthoods. For proper operation, the drafthood outlet must be connected to the venting system.

Vent Piping

WARNING: Indoor boilers require a drafthood that must be connected to a vent pipe and properly vented to the outside. Failure to follow this procedure can cause fire or fatal carbon monoxide poisoning.

Vent piping the same size or larger than the drafthood outlet is recommended, however, when the total vent height is at least 10 ft. (drafthood relief opening to vent terminal), the vent pipe size may be reduced as spec- ified in Chapter 10 of the latest edition of the National Fuel Gas Code, ANSI Z223.1.

As much as possible, avoid long horizontal runs of vent pipe and too many elbows. If installation requires horizontal non-vertical runs, the vent pipe must have a minimum of 1/4 inch per foot rise and should be sup- ported at not more than 5 ft. intervals. Plumbers tape, criss-crossed, will serve to space both horizontal and vertical piping.

Gas vents supported only by the flashing and extend- ing above the roof more than 5 ft. should be securely guyed or braced to withstand snow and wind loads.

We recommend the use of insulated vent pipe spacers through the roof and walls.

For protection against rain or blockage by snow, the vent pipe must terminate with a vent cap which com- plies with the local codes or, in the absence of such codes, to the latest edition of the National Fuel Gas Code, ANSI Z223.1.

The discharge opening must be a minimum of 2 ft. ver- tically from the roof surface and at least 2 ft. higher than any part of the building within 10 ft.

Vent stack shall be at least 5 ft. in vertical height above the drafthood outlet. The vent cap location shall have a minimum clearance of 4 feet horizontally from, and in no case above or below, unless a 4-foot horizontal distance is maintained, from electric meters, gas meters regulators and relief equipment.

The weight of the vent stack or chimney must not rest on boiler drafthood. Support must be provided in com- pliance with applicable codes. The boiler top and drafthood must be readily removable for maintenance and inspection. Vent pipe should be adequately sup- ported to maintain proper clearances from combustible construction.
