SECTION ONE – Heater Design and Function
The heater is operated through an externally mounted
Operating Control Center. Pool and spa settings, a digi-
tal temperature display, and system operation indicator
LEDs are located on the touch-sensitive Membrane Pad
(see Figure 1-3). The indicator LEDs monitor a series of
electronically controlled safety interlocks.
The function of each Operating Control is listed below.
Each indicator light function is listed at right.
NN
NNOO OOTT TTEE EE:::: When either the TEMP
▲ or TEMP ▼ touch
pads are pressed, the digital display will indicate the
temperature setting. After five seconds the display
returns to the actual current pool or spa temperature
(depending on “Pool On” or “Spa On” setting).
To toggle the display between degrees Centigrade (°C)
and degrees Farenheit (°F): press the OFF button; then
press TEMP ▲ or TEMP ▼ for 5 seconds. The display will
flash once and change modes (°C to °F or vice versa).

property damage.
Warranty is void if heater has been improperly
installed, serviced, or maintained.
Explosion hazard with Propane gas
heaters. Propane gas is heavier than air and will
settle to the ground or floor. Do not install a
heater using Propane gas in pits or other loca-
tions where gas might collect. Follow the require-
ments for heater location as specified by the Standard
for Storage and Handling of Liquifed Petroleum
Gases, ANSI/NFPA 58 (latest edition) so that the
heater is installed a safe distance from Propane gas
storage and filling equipment.

There are two reasons for the clearances given here.
They are:
1. Adequate clearance from combustibles to avoid a
fire hazard.
2. Adequate air circulation around the heater to avoid
overheating.
Adequate working room for ease of maintenace will
depend on the installation.
Locate the heater on a level surface in an open,
unroofed area that is protected from drainage or run-
off. Install the heater in an area where leaves or other
debris will not collect on or around the heater. Do not
install the heater where water (including rain, sprin-
klers, or runoff) will fall directly onto the heater jacket.

Risk of explosion if a Propane gas unit is
installed in a pit or other low spot. Propane gas is heavier
than air. Do not install the heater using Propane gas in pits
or other locations where gas might collect. Consult your local
building code officials to determine installation requirements
of heater relative to Propane gas storage tanks and filling
equipment. Installation must meet National Fuel Gas Code
requirements. Consult local codes and fire protection authori-
ties about specific installation restrictions.
Risk of fire and explosion if installed at
floor level in an automotive garage or near gasoline or
flammable liquid storage. In a utility room or residential
garage, install the heater with the base at least 18” above the
floor so that the bottom of the combustion chamber and ignit-
er will be at least 20” off the floor.
Risk of asphyxiation if exhaust is not cor-
rectly vented. Follow venting instructions exactly when
installing heater. Do not use a draft hood with this
heater.
Risk of carbon monoxide poisoning. DO
NOT operate heater if vent faults are detected. Correct
any vent faults before operating heater.

SECTION TWO – Heater Installation
Indoor (U.S.) and Outdoor
Shelter (Canada) Installation
Instructions
The heater is design certified by CSA for installation on
combustible flooring; in alcoves; in basements; in clos-
ets or utility rooms (in the U.S.).
In Canada, this pool heater can only be installed out-
doors or in an enclosure (“outdoor shelter”) that is not
normally occupied and does not directly communicate
with occupied areas.
For installation on carpeting, the heater must be mount-
ed on a metal or wood panel that extends at least three
inches (10 cm) beyond the base of the heater. If the
heater is installed in a closet or alcove, the entire floor
must be covered by the panel.
Explosion hazard with Propane gas
heaters. Propane gas is heavier than air and will
settle to the ground or floor. Do not install a heater
using Propane gas in pits or other locations where
gas might collect. Follow the requirements for heater
location as specified by the Standard for Storage and
Handling of Liquifed Petroleum Gases, ANSI/NFPA 58
(latest edition) so that the heater is installed a safe dis-
tance from Propane gas storage and filling equipment.

Risk of fire and explosion if installed at
floor level in an automotive garage or near gasoline
or flammable liquid storage. Gasoline fumes are
heavier than air and will settle to floor level in closed
spaces. Gasoline fumes and spilled gasoline or other
volatile liquids (such as some paints and varnishes)
will travel across the floor and can be ignited by a gas
appliance. In a utility room or residential garage installa-
tion, install the heater with the base at least 18 inches
above the floor, so that the burner and ignition device
will be at least 20 inches above the floor (see Figure
2-5). In a garage, install a rail or wall to protect the
heater from physical damage by a moving vehicle.

Risk of asphyxiation if exhaust is not
correctly vented. Follow venting instructions exact-
ly when installing heater. Do not use a draft hood
with this heater, as the exhaust is under pressure from
the burner blower and a draft hood will allow exhaust
fumes to blow into the room housing the heater.
Exhaust venting to the outdoors is required for all
indoor and outdoor shelter (“enclosed”) installations.
DO NOT common vent this heater with another
appliance.
DO NOT substitute or modify parts in the venting
system.
Enclosed installation requires venting to the outside.
On an enclosed installation, the exhaust discharges
from the Vent Body into a vent pipe. Locate the heater
so the vent run is as short and straight as possible.
Orient the heater so that the vent pipe does not inter-
fere with adjustment of the operating controls. The
operating control panel located on top of the jacket can
be rotated for easy access.

NNOO OOTT TTEE EE:::: Combustion air contaminated by corrosive
chemical fumes can damage the heater and will void
the warranty.
Combustion and Ventilation
Air Supply
For indoor installation, the heater requires air supply
openings for ventilation and combustion. The mini-
mum requirements are for two (2) openings: one 12
inches from the ceiling for ventilation air and one 12
inches from the floor for combustion air, in accordance
with the latest edition of the National Fuel Gas Code,
ANSI Z223.1., and any local codes that may apply.
The minimum net free area in square inches shall be
as follows:

Air Requirements
Indoor Vent Installation
Always vent the heater to the outdoors.
• Vent it horizontally or vertically using Special Gas
Vent, (see Table 2-G, Page 2-10), or
• Vent it vertically using Type “B” double wall vent
connector pipe.
Locate the heater so as to minimize the length of hori-
zontal vent pipe and the number of vent elbows
required. Horizontal vent runs must slope up 1/4"per
foot from the heater to allow exhaust condensate to
drain and must have a condensate drain as described in
the venting installation instructions.

3. Attach the vent pipe to the Metal Flue Collar with
sheet-metal screws.
Risk of fire or asphyxiation if vent is
not assembled according to manufacturer’s instruc-
tions or if vent parts from different manufacturers
are mixed. Vent parts from different manufacturers
ARE NOT interchangeable. Mixing parts from more than
one manufacturer may cause leaks or damage to vent.
When assembling a vent, pick one manufacturer and be
sure that all vent parts come from that manufacturer
and are specified by the manufacturer for your system.
Follow manufacturer’s instructions and local and
National Fuel Gas Code requirements carefully during
assembly and installation.
4. Install vent pipe so that it can expand and contract
freely as the temperature changes. Support the vent
pipe according to applicable codes and the vent
manufacturer’s instructions. Pipe support must
allow the vent pipe free movement out and back,
from side to side, or up and down as necessary,
without putting a strain on the heater or vent body.
Slope horizontal pipe runs up from the heater at
least 1/4"per foot (2 cm/meter). Install Listed con-
densate drains at low points where condensate
might collect. Plumb condensate drains to a drain
through hard piping or high-temperature tubing
such as silicone rubber or EPDM rubber – do not
use vinyl or other low temperature tubing. Follow
drain manufacturer’s installation instructions.
5. Use Listed firestops for floor and ceiling penetra-
tions. Use Listed thimble for wall penetrations. Use
a Listed roof flashing, roof jack, or roof thimble for
all roof penetrations. Do not fill the space around
the vent (that is, the clear air space in the thimble
or firestop) with insulation. The roof opening must
be located so that the vent is vertical.
6. See Table 2-F (Page 2-7) for height of vent termina-
tion above the roof (U.S.) and Figure 2-7 (Page 2-7)
for U.S. venting requirements. See Figure 2-8 (Page
2-7) and Standard CSA-B149.1 for Canadian vent-
ing requirements.
7. Do not run the heater vent into a common vent
with any other appliance.

vent pipe according to applicable codes and vent
manufacturer’s instructions. Pipe support must
allow the vent pipe free movement out and back,
from side to side, or up and down as necessary,
without putting a strain on the heater or Vent
Body. Slope horizontal pipe runs up from the
heater at least 1/4” per foot. Install Listed conden-
sate drains at low points where condensate might
collect. Plumb condensate drains to a drain
through hard piping or high-temperature tubing
such as silicone rubber or EPDM rubber – do not
use vinyl or other low temperature tubing. Follow
drain manufacturer’s installation instructions.
5. Use Listed firestops for floor and ceiling penetra-
tions. Use Listed thimble for wall penetrations. Use
a Listed roof flashing, roof jack, or roof thimble for
all roof penetrations. Do not fill the space around
the vent (that is, the clear air space in the thimble
or firestop) with insulation. The roof opening must
be located so that the vent is vertical.
6. Vent Termination – Vertical (See Table 2-F, Page
2-9, for height of vent termination above the roof
in the U.S. See Table 2-J, Page 2-12, for Listed ter-
minations.) Use a Listed vent terminal specified by
local and national codes and your manufacturer’s
instructions. A roof termination must be vertical.
In Canada, the Vent Cap location must have a min-
imum clearance of 4 feet (1.2 M) horizontally from
electric meters, gas meters, regulators, and relief
openings.
7. United States Vent Termination – Horizontal (See
Table 2-J). Use a listed wall thimble and vent termi-
nal from Table 2-J.
In the U.S. the terminal must be located
(see Figure 2-10, Page 2-10):
• at least 3"and at most 12" out from the wall (see
Figure 2-10), following the vent manufacturer’s
instructions.
• at least 12"above finished grade or the normally
expected snow accumulation level, whichever is
higher.
