Breckwell P22FSL Gas Heater User Manual


 
Equivalent Vent Length (EVL)
The longer the run of pipe in your installation (both with inserts and
freestandings), the more restriction there is in the system. Therefore,
larger diameter pipe should be used.
Use 4” pipe if you have more than 15 feet of equivalent vent
length.
Horizontal runs shall not exceed 10 feet of EVL.
It is recommended that vertical runs be a minimum of 8 feet.
To calculate EVL, use the following conversions:
90º elbow or “T” = 5 equivalent feet
45º elbow = 3 equivalent feet
Horizontal Pipe Run = 1 equivalent foot per actual foot
Vertical Pipe Run = 0.5 equivalent foot per actual foot
NOTE: At altitudes above 3,000 feet, we suggest the use of 4”
diameter vent at an EVL of 7 feet or more.
FREESTANDING INSTALLATIONS
A. ASSEMBLING PEDESTAL OR LEG SET
If using a pedestal, follow the instructions inside the Breckwell P22
Pedestal Set Part # A-22-P (refer to figure 8).
If using cast legs, follow the instructions inside the Breckwell P22 Leg
Set Part # A-CGL-22 or # A-CL-22.
Legs are installed by using the four bolts provided in the kit into the
four holes under the stove at each corner, thread on nuts from the top
and tighten. Make sure to save the hole plugs.
NOTE: If converting from legs to pedestal the hole plugs must be
installed in the unused holes.
B. HORIZONTALLY THROUGH WALL (refer to Figure 9)
NOTE: See “VENTING” and follow L-Vent chimney manufacturer’s
instructions.
1. Position stove, adhering to clearances shown in Figures 1 & 2.
2. Locate position of hole in wall; directly behind stove exhaust vent
(refer to figure 5).
3. Always maintain 3” clearance from combustible materials.
4. Install L-Vent wall thimble per L-Vent manufacturer’s instructions.
5. Attach enough piping to penetrate and extend at least 6” beyond
exterior walls. An 8-foot vertical pipe run is suggested where
possible to reduce the possibility of smoke spillage in the event of
a loss of negative pressure.
6. Attach cap and seal outside wall thimbles with non-hardening
waterproof mastic.
7. Termination should not be located so that hot exhaust gases can
ignite trees, shrubs, or grasses or be a hazard to children.
Exhaust gases can reach temperatures of 500ºF and cause
serious burns if touched.
Locate terminations: a) not less than 3 feet above any forced air
inlet located within 10 feet; b) not less than 4 feet below or
horizontally from, or one foot above, any door, window or gravity
air inlet into any building; c) not less than two feet from an
adjacent building and not less than 7 feet above grade when
located adjacent to a public walkway. Mobile home installations
must use a spark arrester.
