Venting Guidelines - ECR International G95V Installation Manual And Operating Instructions

FIGURE 6 - OUTDOOR AIR FOR COMBUSTION,
HORIZONTAL (CASE 4)
IMPORTANT: The outdoor grilles must be
installed in a location where they will not be
obstructed in any manner.
CONNECTION TO FURNACE
NON-DIRECT VENT
When using indoor air or the non-direct vent config-
uration, the combustion air inlet to the furnace must
be protected from blockage. Use a double elbow
arrangement if supplying combustion air through
the top, or a downward pointing single elbow if sup-
plying combustion air through the side. (Figure 7)

11 - VENTING GUIDELINES

!
CAUTION
Failure to follow all venting guidelines may
result in erratic furnace operation, freeze-up
of the exhaust air piping, or sooting of the
furnace.

WARNING
READ AND FOLLOW ALL INSTRUCTIONS
IN THIS SECTION. FAILURE TO PROPERLY
VENT THIS FURNACE CAN CAUSE CARBON
MONOXIDE POISONING OR AN EXPLOSION
OR FIRE RESULTING IN PROPERTY DAM-
AGE, PERSONAL INJURY OR LOSS OF LIFE.
NOTE: Combustion air intake and exhaust termination
should be inspected periodically to ensure they are clear of
obstructions. i.e. vegetation, debris, snow, etc.
NOTE: Accumulation of snow around the combustion air
intake and exhaust termination may have negative effects
on appliance operation and/or performance. Snow accu-
mulation should be considered when locating combustion
air intake and exhaust terminations.
• Venting may be vertical or horizontal.
• Minimum vent length - 25 total equivalent feet.
(See Venting Table)
• Horizontal piping must slope back towards
the furnace at a minimum rate of ¼" to the
foot, so that condensate drains towards the
furnace.
• Horizontal runs must be supported at least ev-
ery 3 feet. Horizontal sections must not dip or
sag.
• All vent runs through unconditioned space
where freezing might occur should be insulated
with 1" thick, medium density, foil-faced Fiber-
glass insulation. An equivalent "arm-a-flex" or
"rub-a-tex" may also be used as long as there is
no heat tape applied to the vent pipe. For hori-
zontal runs where water may collect, wrap the
vent pipe with self regulating 3 or 5 watt heat
tape. The heat tape must be CSA, UL, or ULC
listed and installed per the manufacturer's in-
structions.
• DO NOT COMMON VENT WITH ANY OTH-
ER APPLIANCE.
• If venting vertically, do not vent up a chimney
serving another appliance or install in a chase
with a metal or high temperature plastic pipe
from another gas or fuel burning appliance
unless the required clearances to combusti-
bles can be maintained between the furnace
venting system and other pipes.
