Lochinvar 51 Stainless steel vent, Boiler Flue Intake Air Adapter, Termination

Installation & Operation Manual

3General venting

￿WARNING

NOTICE

Using vent or air intake materials other than those specified, failure to properly seal all seams and joints or failure to follow vent pipe manufacturer’s instructions can result in personal injury, death or property damage. Mixing of venting materials will void the warranty and certification of the appliance.

The use of double-wall vent or insulated material for the combustion air inlet pipe is recommended in cold climates to prevent the condensation of airborne moisture in the incoming combustion air.

When a sidewall or vertical rooftop combustion air supply system is disconnected for any reason, the air inlet pipe must be resealed to ensure that combustion air will be free of contaminants and supplied in proper volume.

￿Failure to properly seal all joints and seams

DANGER

as required in the air inlet piping may result in flue gas recirculation, spillage of flue products and carbon monoxide emissions causing severe personal injury or death.

Stainless steel vent

This product has been approved for use with stainless steel using the manufacturers listed in Table 3A.

Sealing of Type “B” double-wall vent material or galvanized vent pipe material used for air inlet piping on a sidewall or vertical rooftop Combustion Air Supply System:

a.Seal all joints and seams of the air inlet pipe using either Aluminum Foil Duct Tape meeting UL Standard 723 or 181A-P or a high quality UL Listed silicone sealant such as those manufactured by Dow Corning or General Electric.

b.Do not install seams of vent pipe on the bottom of horizontal runs.

c.Secure all joints with a minimum of three sheet metal screws or pop rivets. Apply Aluminum Foil Duct Tape or silicone sealant to all screws or rivets installed in the vent pipe.

d.Ensure that the air inlet pipes are properly supported.

￿WARNING

NOTICE

Use only the materials, vent systems, and terminations listed in Table 3B. DO NOT mix vent systems of different types or manufacturers, unless listed in this manual. Failure to comply could result in severe personal injury, death, or substantial property damage.

Installations must comply with applicable national, state, and local codes. Stainless steel vent systems must be listed as a UL-1738 approved system for the United States and a ULC-S636 approved system for Canada.

The PVC, CPVC, or ABS air inlet pipe should be cleaned and sealed with the pipe manufacturer’s recommended solvents and standard commercial pipe cement for the material used. The PVC, CPVC, ABS, Dryer Vent or Flex Duct air inlet pipe should use a silicone sealant to ensure a proper seal at the appliance connection and the air inlet cap connection. Dryer vent or flex duct should use a screw type clamp to seal the vent to the appliance air inlet and the air inlet cap. Proper sealing of the air inlet pipe ensures that combustion air will be free of contaminants and supplied in proper volume.

NOTICE	Installation of a stainless steel vent system
	should adhere to the stainless steel vent
	manufacturer’s installation instructions
	supplied with the vent system.
	The installer must use a specific vent starter
NOTICE
	adapter at the flue collar connection,
	supplied by the vent manufacturer to adapt
	to its vent system. See Table 3B for approved
	vent adapters. Discard CPVC starter piece.

*= This adapter must be used in addition to the boiler adapter for Saf-T vent pipe as shown in FIG. 3-10, unless approved vent other than standard diameter is used. Consult a Heat Fab representative for questions.

**The stainless steel venting option is only available in 3" vent diameters.
