B. Check inside the bottom of the vent pipe to make sure the top of the draft diverter did not

rip the inner liner causing it to block part of the vent opening.

C. Check that no insulation from the header plate got caught on top of the draft diverter when

the heater was inserted into the wall.

D. Check that the vent cap is properly installed, not shoved too tar down on the vent pipe.

wiring harness

A. The vent should tenninate a minimum of 12 feet above the floor. See Figure 2. Also, the

top of the vent must be at least 2 foot above any obstacle within a 10 foot radius, including

the roof. See Figure A.

B. All type "B" vents shall extend in a generally vertical direction with ofl;ets not exceeding 45

degrees, except that a vent system having not more than one 60 degree ofl;et may be allowed.

Any angle greater than 45 degrees tiom the vertical is considered horizontal.

The total

horizontal mn of a vent plus the horizontal vent connector shall be not greater than 75 percent

of the vertical height of the vent.

Any ofl_ets used should be as far above the drafthood as possible to allow a venting action to

begin before any restriction is encountered.

C. Use listed BW type vent pipe. Do not use tansite or any other type of ceramic pipe t\_r venting.

Do not use single wall pipe. When venting into a masonry chimney the chimney must be

properly lined and sized for this gas furnace. The use of type B or flexible chimney liner is

recommended.

The header plate must be 65-3/4" above the floor plate. See rough-in instructions.
