Masonry Chimney
This furnace can be vented into an existing masonry chimney.
However, it must not be vented into a chimney servicing a solid fuel-
burning appliance. Before venting this furnace into a chimney, the
chimney must be checked for deterioration and repaired if
necessary. The chimney must be properly lined and sized per local
or national codes.
If the furnace is vented into a common chimney, the chimney must
be of sufficient area to accommodate the total flue products of all
appliances vented into the chimney.
The following requirements are provided for a safe venting system :
a.
Ensure that the chimney flue is clear of any dirt or debris;
b.
Ensure that the chimney is not servicing an open fireplace;
c.
Never reduce the pipe size below the outlet size of the furnace;
d.
All pipes should be supported using the proper clamps and/or
straps. These supports should be at least every 1.2 m (4
')
;
e.
All horizontal runs of pipe should have at least a 20 mm per
1 m (1/4
"
per foot
)
upward slope;
f.
All runs of pipe should be as short as possible with as few turns
as possible;
g.
Seams should be tightly joined and checked for leaks;
h.
The flue pipe must not extend into the chimney but be flush
with the inside wall;
i.
The chimney must extend 0.9 m (3
')
above the highest point
where it passes through a roof of a building and at least 0.6 m
(2
')
higher than any portion of a building within a horizontal
distance of 3.0 m (10
')
. It shall also be extended at lest 1.5 m
(5
')
above the highest connected equipment flue collar;
j.
Check local codes for any variances.
Factory Built Chimneys
This furnace may be used with an approved, factory built chimney.
Refer to chimney manufacturer’s instructions for proper installation.
1.5) COMBUSTION
AIR
6
WARNING
Poisonous carbon monoxide gas hazard.
Comply with ANSI/NFPA (in U.S.) or CSA (in
Canada) standards for the installation of Oil
Burning Equipment and applicable provisions of
local building codes to provide combustion and
ventilation air.
Failure to provide adequate combustion and
ventilation air can result in personal injury and/or
death.
1.5.1) General
Oil furnaces must have an adequate supply of combustion air. It is
common practice to assume that older homes have sufficient
infiltration to accommodate the combustion air requirement for the
furnace. However, home improvements such as new windows,
doors,
and weather stripping have drastically reduced the volume of air
infiltration into the home.
Home air exhausters are common. Bathroom and kitchen fans, power
vented clothes dryers, and water heaters all tend to create negative
pressure in the home. Should this occur, the chimney becomes less
and less effective and can easily downdraft.
Heat recovery ventilation (HRV) systems are gaining in popularity.
HRVs are not designed to supply combustion air. If not properly
balanced, a serious negative pressure condition could develop in the
dwelling.
1.5.2) Contaminated Combustion Air
Installations in certain areas or types of structures will increase the
exposure to chemicals or Halogens, which may harm the furnace.
These instances will require that only outside air be used for
combustion.
The following areas or types of structures may contain or be exposed
to the substances listed below. The installation must be carefully
evaluated as it may be necessary to provide outside air for
combustion.
a. Commercial
buildings;
b.
Buildings with indoor pools;
c.
Furnaces installed near chemical storage areas.
Exposure to these substances:
a.
Permanent wave chemicals for hair;
b.
Chlorinated waxes and cleaners;
c.
Chlorine based swimming pool chemicals;
d.
Water softening chemicals;
e.
De-icing salts or chemicals;
f. Carbon
tetrachloride;
g.
Halogen type refrigerants;
h.
Cleaning solvents (such as perchloroethylene);
i.
Printing inks, paint removers, varnishes, etc. ;
j. Hydrochloric
acid;
k. Solvent
based
glues;
l.
Antistatic fabric softeners for clothes dryers;
m. Acid based masonry cleaning materials.
1.6)
OIL TANKS AND LINES
Check your local codes for the installation of the tank and accessories.
A manual shut-off valve and an oil filter shall be installed in sequence
from tank to burner. Be sure that the oil line is clean before connecting
to the burner. The oil line should be protected to eliminate any
possible damage. Installations where the fuel oil tank is below the
burner level must employ a two pipe fuel supply system with an
appropriate fuel pump. For more than an 2.4 m (8') rise use a 2 stage
pump and for more than a 4.9 m (16') rise use an auxiliary pump.
Follow the pump instructions to determine the size of tubing you need
in relation to the rise, or the horizontal distance.
Inspect the entire oil distribution system for leaks at the beginning of
each heating season.
1.7) BURNER
INSTALLATION
Mounting the burner
1. The warm air furnace burner mounting plate has a 4-bolt
configuration;
2.
Position the mounting gasket between the mounting flange and
the appliance burner mounting plate. Line up the holes in the
mounting flange with the studs on the appliance mounting plate
and securely bolt in place.
