INSTALLATION INSTRUCTIONS
Location
This water heater should be located as close as
possible to a chimney and to the main use of hot
water. This location must not be subject to freezing
temperatures. The water heater should be
positioned, so that there is easy access to the oil
burner, controls and drain valve. It must be located
close to a suitable free-flowing floor drain. Where a
floor drain is not adjacent to the water heater, a
suitable drain pan must be installed under the water
heater (see Figure 10). This drain pan should be at
least four (4) inches (10.2 cm) larger than the
diameter of the water heater, and at least one (1)
inch (2.5 cm) deep, providing access to the drain
valve. This pan must not restrict the flow of
ventilation and combustion air. This pan must be
piped to a suitable drain to prevent damage to
property in the event of a water leak from the piping,
the relief valve or the water heater.
Based on national building codes, the manufacturer has given the necessary instructions to prevent damage to the building. Under no circumstances is the manufacturer to be held liable for
any water damage in connection with this water
heater.
This water heater can be installed in a storage or
residential garage if it is installed at least 18 inches
(460 mm) above floor level and protected against
physical damage.
This water heater is NOT approved for installation
on a combustible floor.
Minimum Clearances
The minimum clearances from combustible material
for this water heater are: Two (2) inches (5.1 cm)
from the sides and rear, twenty-four (24) inches
(61.0 cm) from the front, eighteen (18) inches (45.7
cm) from the top, and nine (9) inches (22.9 cm) from
the vent pipe (eighteen (18) inches (45.7 cm) for
water heaters installed in the United States) (see
Figure 1).
Combustion and Ventilation Air Supply
In order for the water heater to operate properly, it
must be supplied with an uninterrupted flow of clean
combustion and ventilation air. The area around the
water heater must always be kept clean and clear of
debris. An inadequate supply of air to the water heater
will produce a bright yellow burner flame causing sooting in the combustion chamber, on the burner, and in
the flue tube. This can result in damage to the water
heater and personal injury, if not corrected.
Combustion and ventilation air requirements are
determined by where the water heater is located.
Water heaters are installed in either open (unconfined) spaces or smaller (confined) spaces, such as
closets or small rooms.
IMPORTANT
These instructions have been written as a guide for the proper installation and operation of your water heater and
the manufacturer of this water heater will not accept any liability where these instructions have not been followed.
However, for your safety and to avoid damage caused by improper installation, this water heater must be installed
by a Certified Licensed Professional and meet all local codes or, in the absence of such codes, the latest edition of
CAN/CSA B139, Installation for Oil Burning Equipment, in Canada, and/or the latest edition of Standard for the
Installation of Oil Burning Equipment, NFPA 31, in the United States. For Mobile Home installation in Canada, all relevant Clauses of “CAN/CSA Z240MH – Manufactured Homes” must be followed. All models are CSA listed for use with
No.1 (stove) and No. 2 (furnace oil).
Before proceeding with the installation instructions:
1)
Inspect the water heater and its component parts for possible damage. Do not install or attempt to repair any damaged
component parts. If you detect any damage, contact the dealer where the water heater was purchased or the manufacturer
listed on the warranty card.
2)
Verify that the type of oil being supplied corresponds to what is marked on the rating plate of the water heater. DO NOT
install if the water heater or parts of the water heater have been damaged.
WARNING
Requirements for Unconfined Spaces
Water heaters installed in unconfined spaces do not
usually require outdoor air to function properly.
However, if the water heater is located in an unconfined space in a building having insufficient
infiltration, air for combustion and additional ventilation
should be obtained from the outdoors or from spaces
freely communicating with the outdoors (see Figure
2). Under these conditions, a permanent opening to
the outdoors should be provided so that the total air
received through this opening will be at least as much
as would be admitted by openings having a total freeflow area of one (1) square inch per 5,000 BTU/h (4.4
cm
2
/kWh) of the total input rating of all oil-fired appli-
ances.
Requirements for Confined Spaces (Indoor
Combustion and Ventilation Air)
A water heater that is located in a confined space and
obtains all of its air for combustion and ventilation from
within the conditioned space of the building should be
provided with two permanent openings, one near the
top of the enclosure and another one near the bottom
(see Figure 3). Each opening should have a free-flow
area of not less than one (1) square inch per 1,000
BTU/h (22 cm
2
/kWh) of the total input rating of all
oil-fired appliances in the enclosure, freely communicating with interior areas that have in turn adequate
infiltration from the outdoors.
Requirements for Confined Spaces (Outdoor
Combustion and Indoor Ventilation Air)
A water heater that is located in a confined space and
that obtains its combustion air from outdoors and
ventilation air from within the conditioned space of
the building should be provided with two permanent
openings, one near the top of the enclosure and
another one near the bottom (see Figures 4 and 5).
Each opening should have a free-flow area of not less
than one (1) square inch per 1,000 BTU/h (22
cm
2
/kWh) of the total input rating of all oil-fired appliances in the enclosure, freely communicating with
interior areas that have in turn adequate infiltration
from the outdoors. A combustion air supply opening
to the outdoors should be provided so that the total air
received through the opening will be at least as much
as would be admitted by openings having a total freeflow area of one (1) square inch per 5,000 BTU/h (4.4
cm
2
/kWh) of the total input rating of all oil-fired appliances in the enclosure.
Requirements for Confined Spaces (Outdoor
Combustion and Ventilation Air)
A water heater that is located in a confined space and
that obtains all of its air for combustion and ventilation
from outside the building shall be provided with two
permanent openings, one near the top of the

enclosure and another one near the bottom (see
Figures 6 and 7). Each opening shall communicate
directly or by means of ducts with the outdoors or to
such spaces (such as a crawl space) that freely communicate with the outdoors and shall be sized in
accordance with the instructions in the section
Air
Duct Sizing.
Air Duct Sizing
The air duct requirements should be met by one of the
following methods:
(a) vertical duct(s) with a free-flow area of not less
than one (1) square inch per 4,000 BTU/h (5.5
cm
2
/kWh) of the total input rating of all oil-fired
appliances in the enclosure;
(b) horizontal duct(s), as shown in Figure 7, with an
equivalent length of less than 50 ft (15 m), having
a free-flow area of not less than one (1) square
inch per 2,000 BTU/h (11 cm2/kWh) of the total
input of all oil-fired appliances in the enclosure; and
(c) air openings that communicate directly with the
outdoors, as shown in Figure 6, having a free-flow
area of not less than one (1) square inch per 4,000
BTU/h (5.5 cm2/kWh) of the total input rating of all
oil-fired appliances in the enclosure.
Note: Duct runs that are primarily horizontal and that
have an equivalent length greater than 50 ft (15 m)
should be sized larger as required to provide
the same airflow as would be provided by the
requirements of Item (b).

INSTALLATION INSTRUCTIONS
Louvers and Grilles
In calculating free area for ventilation and combustion air supply openings, consideration must be
given to the blocking effect of louvers, grilles or
screens protecting the openings. Screens must not
be smaller than 1/4 inch (6.4 mm) mesh. If the free
area through a particular design of louver or grille is
known, it should be used in calculating the size of
opening required to provide the free area specified.
If the design and free area is not known, it may be
assumed that wood louvers and grilles will allow 2025% free area and metal louvers and grilles will allow
60-75% free area. Louvers and grilles must be
installed in the open position or interconnected with
the water heater so that they are opened automatically during water heater operation.
Corrosive Atmospheres
If this water heater is to be installed in a beauty shop,
barber shop, photo processing lab, dry cleaning
establishment, a building with an indoor pool or near
a chemical storage area, it is imperative that the
combustion and ventilation air be drawn from outside
these areas. These particular environments contain
products such as aerosol sprays, detergents, bleaches, cleaning solvents, refrigerants, and other volatile
compounds that, in addition to being highly flammable, become highly corrosive acid compounds when
burned. Exposure to such compounds can be
hazardous and lead to premature product failure.
Should the water heater fail, due to exposure to
such a corrosive atmosphere, the warranty is
void.
Venting
When installing the venting system, make sure to
follow all local codes or, in the absence of such
codes, the latest edition of the CAN/CSA B139,
Installation for Oil Burning Equipment, in Canada,
and/or the latest edition of Standard for the
Installation of Oil Burning Equipment, NFPA 31, in
the United States. Never operate the water heater
unless it is properly ventilated to the outdoors and
has adequate air supply for proper operation.Failure
to properly install the venting system could result in
property damage, personal injury or death.
Chimney Requirements
If this water heater is operated with a burner designed
for natural draft venting, it must be connected to a vertical chimney. The chimney must be properly constructed and sized, clean and free of soot,
creosote and obstructions, able to generate sufficient
draft to evacuate the products of combustion
outdoors and be lined with a tile or metal liner. Inspect
the chimney and make any repairs necessary before
installing the water heater.
To prevent downdrafts, the chimney flue should
extend at least three (3) feet (1 m) above the highest
point at which the chimney comes in contact with
the roof and not less than two (2) feet (0.6 m) above
the highest roof surface or structure within ten
(10) feet (3 m) of the chimney on a horizontal plane
perpendicular to the chimney. Not more than four
(4) inches (100 mm) of chimney flue above the top of
the chimney cap should be considered in computing
this height (see Figure 8). Increase the cross-sectional
area and height of the chimney at least 4% per 1,000
feet (305 m) above sea level.
Failure to properly inspect and repair the chimney
could result in property damage, personal injury or
death.
Flue Piping
Before installing the flue piping, make sure that the
venting system layout has been properly planned.
Make sure that the flue baffle has been installed in the
flue tube. If the baffle is not present, immediately contact the dealer where the water heater was purchased.
NEVER operate the water heater without the flue baffle installed. Verify that the location of the water heater
and the venting system respects all clearances from
combustible materials (see Figure 1).
The length of flue pipe to vent this water heater should
be as short as possible with horizontal runs sloping
upward towards the chimney at a rate of at least
one-quarter (1/4) inch per foot (21 mm/m). Long horizontal runs of flue pipe, sharp turns and other construction features that could create excessive resistance to the flow of flue gas should be avoided. The
flue pipe must not be smaller in cross sectional area
that the flue collar on the water heater. The flue pipe
must not pass through any floor or ceiling, but may
pass through a wall where suitable fire protection
provisions have been installed. The flue pipe should
connect to the chimney such that it extends into, and
terminates flush with, the inside surface of the
chimney liner. The joint between the flue pipe and the
chimney liner should be sealed and all unused
chimney opening should be closed.
