WARNING:
Insulation shall not be used on plastic pipes.
9
WARNING:
Insulation or other materials shall not be within
the required clearance spaces surrounding the vent unless
specified in the vent manufacturer’s installation instructions.
- Venting Options:
Due to potential moisture build-up
along the exterior wall or overhangs, the location of
sidewall venting must be carefully selected.
9
WARNING:
extra precaution must be taken to adequately
support the weight of the Vent/Air-inlet piping in
applications using roof-top terminations. Failure to follow
these instructions may result in venting or boiler component
failure resulting in flue gas spillage leading to property
damage, serious injury or death.

WARNING:
Failure to follow the instructions below may result
in substantial property damage, severe personal injury or
death.
Vent piping outside the building is permitted under the following
conditions:
1. The maximum length outside the building is 7 ft. Note that out-
door length must be included in the overall vent length cal-
culation.
2. All normal termination clearances are maintained.
3. The pipe is supported every 24 in.
4. The exhaust and inlet are sloped back to the boiler ½ in. ele-
vation for every linear foot.
5. The air-inlet and vent pipe must be located in a area where it
cannot be contacted or tampered with.
Existing Chimney Chase Way
It is permissible to use an existing chimney as a chase way to
run the Vent/Air-inlet piping as long as:
1. The chimney is not being used by any other appliance.
2. Flue gases do not enter the vacant chimney.
3. Only Family PRO approved vent manufacturer’s venting
shown in section 8.9 can be used.
Vent lengths are within the maximums specified.
4. The top of the chimney is capped and the Vent Air-inlet pi-
pes are flashed to prevent leakage into the vacant chimney.
Under no circumstances may an existing chimney or chase-way
be used to vent or provide combustion intake air to the FAMILY
PRO. The existing chimney or chaseway can only be used as
a passageway to allow the approved venting material to pass
through. Failure to follow these instructions will result in fire,
property damage, serious injury or death.

Combustion Air and Ventilation Openings
Provisions for combustion and ventilation air must be made in
accordance with section 5.3, Air for Combustion and Ventilation, of
the National Flue Gas Code, ANSI Z223.1/NFPA 54, or Sections 7.2, 7.3
or 7.4 of CAN/CGA B149.1, Installation Codes, or applicable provisions
of the local building codes.

CAUTION
: BOILER DAMAGE AND OPERATIONAL FAILURES!
Provisions for combustion air and ventilation are always
required through a grille, regardless whether the combustion
air is taken from the outside (sealed combustion).
9
Make sure that intake and exhaust openings are sufficiently
sized and no reduction or closure of openings takes place.
If this is not the case, then the problem is not resolved, do not
operate the boiler.
− Please note these restrictions and its dangers to the operator of
the boiler.

WARNING
: BOILER DAMAGE !
− Boiler must be clear and free from combustible materials,
gasoline and other flammable vapors and liquids, and corrosive
liquids and vapors. Never use chlorine and hydrocarbon
containing chemicals (such as spray chemicals, solution and
cleaning agents, paints, glues etc.) in the vicinity of the boiler.
− Do not store and use these chemicals in the boiler room.
− Avoid excessive dust formation and build-up.
