To calculate EVL use following formula:
for each 90 Elbow or T fitting = add 5 EVL
for each 45 Elbow = add 3 EVL
for each Horizontal run of vent = add 1 EVL per foot of horizontal venting
for each Vertical run of vent = add 1/2 EVL per foot of vertical venting
YOU MUST USE 4” STAINLESS STEEL RIGID OR FLEXIBLE VENT PIPE IF:
The EVL is 7 or more AND your are at or above an altitude of 3000 ft.
OR
The EVL is 15 or more
OR
Your unit is an Insert
DO NOT USE MAKESHIFT MATERIALS OR COMPRO-
MISES IN THE INSTALLATION. IT IS A FIRE HAZARD.
Exhaust vent pipes are located on the exhaust side of the exhaust fan and are under
positive pressure. Care must be taken to ensure that all joints are completely sealed to
prevent any leakage of exhaust fumes into the house. If you smell smoke, the venting
has not been properly sealed. Use only high temperature RTV silicone for sealing.
4.2 Combustion Air Intake Requirements
A. It is mandatory to use outside air for combustion in ALL mobile or
manufactured home installations.
B. Conventional homes may use APR Part No: CV100 check valve in
order to use internal combustion air. If a check valve is not used, the
air intake of this heater must be connected to the exterior of the
building using a non-combustible metal pipe, with a minimum 2 inch
(50mm) diameter. Use of plastic pipes are not permitted.
C. The combustion air intake must terminate into a vented space, i.e.
outside, vented attic, or vented crawl space. This heater CAN NOT
draw air from a closed space such as a closed garage, airtight crawl
space or any other sealed room.
D. The elevation of the combustion air intake must be below the exhaust
vent. An elbow may be used to lower the air intake point below that of
the exhaust vent.
F. Excessive lengths and elbows on the air intake pipe will cause airflow
restrictions. A minimum of 2 inch, or larger, venting should be used
for longer lengths. Increase the venting size as needed.
