!

NOTICE

Terminals should be positioned as to avoid products of combustion entering openings into buildings or other vents.

Maintain 12” of clearance above the highest anticipated snow level or grade or, whichever is greater. Please refer to your local codes for the snow level in your area.

CAUTION

The termination shall be at least 4 feet (1,220 mm) for the US and 6 feet (1,830

 

mm) for Canada distance from electric meters, gas meters, regulators and

 

relief equipment. (for room air application only)

NOTICE

Horizontal vent systems should always be installed sloping towards the

boiler (min. 21 mm/m, 1/4 “/ feet), in order to avoid condensate retaining in

 

the vent system. With the condensate running back to the boiler the risk of

 

ice forming at the terminal is reduced.

NOTICE

The whole route of the vent system must be installed upwards, never

 

downwards, completely nor partly.

NOTICE

Place pipe supports every 4 feet (1219 mm) of horizontal run, beginning with

 

the support near the boiler to prevent movement in fittings and allow boiler

 

to be free from any strain or weight on boiler or fittings.

NOTICE

The terminal should be located where dispersal of combustion products is

 

not impeded and with due regard for the damage or discolouration that might

 

occur to building products in the vicinity (see fig 14 and 15).
