FOR YOUR SAFETY - READ BEFORE OPERATING
WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION MAY
RESULT,CAUSINGPROPERTYDAMAGE,PERSONALINJURYORDEATH.
SECTION 1/START-UP PROCEDURES
BEFORE START-UP
WATER
Firstthing,ensurethatsystemisfilledwithwaterand
have pump operating. Water must be flowing through
the heater during operation.
BURNERS
Clean main burners and air louvers of dust, lint and
debris. Keep heater area clear and free from com-
bustibles, flammable liquids and chemicals. Do not
obstruct the flow of combustion and ventilating air.
CAUTION: Propane gas is heavier than air and will
settle on the ground. Since propane can accumulate in
confined areas, extra care should be exercised when
lightingpropaneheaters.

or turn by hand, do not try to repair it; call a qualified
service technician. Force or attempted repair may
result in fire or explosion.
B. BEFORE OPERATING, smell all around the appli-
ance area for gas. Be sure to smell next to the floor
because some gas is heavier than air and will settle
on the floor.
WHAT TO DO IF YOU SMELL GAS:
D. Do not use this appliance if any part has been
under water. Immediately call a qualified service
technician to inspect the appliance and to replace
any part of the control system and any gas control
which has been under water.

only slightly warmer than the inlet. It should not be hot.
Elevatedwatertemperaturecanbehazardous,and
theU.S.ConsumerProductSafetyCommissionrecom-
mends the following guidelines:
WARNING: Should overheating occur or the gas
supply fail to shut off, turn off the manual gas control to
the appliance.
1. Spa or hot tub water temperatures should never
exceed104°F(40°C).Atemperatureof100°F(38°C)
is considered safe for a healthy adult. Special
caution is suggested for young children.
2. Drinking of alcoholic beverages before or during
spa or hot tub use can cause drowsiness which
could lead to unconsciousness and subsequently
result in drowning.
VISUAL INSPECTION
With the heater on, remove the door and make a
visual check of the pilot and burner.
The flame should be blue with a well-defined pat-
tern.
3. Pregnant Women Beware! Soaking in water over
102°F (39°C) can cause fetal damage during the
first three months of pregnancy, resulting in the
birth of a brain damaged or deformed child. Preg-
nant women should stick to the 100°F (38°C)
maximum rule.
4" Max.
4. Before entering the spa or hot tub, users should
check the water temperature with an accurate
thermometer; spa or hot tub thermostats may err in
regulating water temperatures by as much as 4°F
(2.2°C).

using pools or hot tubs.
6. Persons taking medications which induce drowsi-
ness, such as tranquilizers, antihistamines, or anti-
coagulants, should not use spas or hot tubs.
SECTION 3/MAINTENANCE AND CARE
PROCEDURES
PILOT BURNER FLAME
A yellow or “floating” flame indicates restricted air
openings or incorrect orifice size. Should this occur,
shut the heater off and contact your installer or gas
supplier.
To be followed one month after start-up and then semi-
annually.
1. Inspect top of heater and drafthood for soot, (a
sticky black substance around finned tubes and “V”
baffles), and open flue gas passageways.
WATER PRESSURE SWITCH
A water pressure switch is provided in the heater to
shut off the burners in the event that water supply to the
heater is interrupted. It is very important to verify that
the switch electrically opens and shuts off the gas valve
whenwaterflowtotheheaterisinterrupted. Otherwise,
rapid and severe damage will likely occur to the heater.
(The water pressure switch should be checked and
adjusted for proper operation by a qualified service
personatthetimeofinstallationandperiodicallychecked
thereafter. Refer to pressure switch servicing instruc-
tion in Section 4 of this manual).
CAUTION: Soot may be combustible. Wet sooted
surfaces completely prior to cleaning. Do not use steel
wire brush.
2. Cleanmainburnersandpilotburnerofdustandlint.
3. Inspect and operate all controls, gas valve and
pressure relief valve.
4. Make visual check of the burner and pilot flame.
Flame pattern on the main burner and pilot is
indicated in the previous illustration. Yellow flame
means restriction of the air openings. Lifting or
blowing flame indicates high gas pressure. Low
flame means low gas pressure. Should this occur,
shut the heater off and contact your gas supplier or
qualified service agency.

SECTION 2/GENERAL SPECIFICATION
Theseheatersaredesigncertifiedandtestedunder
the requirements of ANSI Z21.56/CSA 4.7 American
NationalStandardforGas-FiredPoolHeaters.
All heaters are inter-changeable and can be used
either indoor or outdoors. The appropriate top desig-
nated for that type of use is required. If desired, the top
can be changed at a later date from outdoor to indoor or
viceversa.
Rated inputs suitable for up to 2000 feet elevation.
Forelevationsabove2000feet,reduceinput4%foreach
1000 feet above sea level, as height elevation reduces
combustionperformance.
CODE REQUIREMENT
NOTE: The heater should not be located in an area
where possible water leakage will result in damage to
the area adjacent to the appliance or to the structure.
When such locations cannot be avoided, it is recom-
mended that a suitable drain pan, adequately drained,
be installed under the appliance. The pan must not
restrict combustion air flow.

WARNING: The heater shall not be located in an area where water sprinklers, or other devices, may cause water
to spray through the cabinet louvers and into the heater. This could cause heavy internal rusting or damage some
electrical components, and this would void the warranty.
The point from where the flue products exit the heater must be a minimum of four (4) feet below, four (4) feet

NOTE: 1. When 2” piping is used into the heater, this
piping must be anchored (copper) or screwed into the
flange (metal) if operating pressures above 30 PSI are
encountered.
2. Any restrictions between heater outlet and
pool will void the warranty.
PLUMBING FOR WATER CONNECTIONS
LOCATION
Theheaterrequireswaterflowandpositivepressure
tofireandoperateproperly. Itmustthereforebeinstalled
downstream of the discharge side of the filter pump. A
typical installation is plumbed as follows:
1. The inlet side of the filter is plumbed directly to
the discharge side of the filter pump;
FLOWRATES
2. The outlet side of the filter is then plumbed to
the inlet of the heater; and
3. Theoutletoftheheaterisplumbedtothereturn
line to the pool or spa. The pump, filter and
heater are thus plumbed in series.

COMPANIONFLANGECONNECTIONS
DO NOT use petroleum base assembly fluids (such as
Petroleum Jelly or lubricating oil). If assembly tube is
required use a silicone base such as Armoral etc.
The inlet/outlet header flange accepts a 2” copper
tube as a slip connection directly into the header. The
flange is also thread for a 2” copper male threaded
adapter.
CAUTION: NEVER install PVC directly into heater.
Four feet of copper or high temperature pipe and two
elbows are required between the heater and the PVC
connections
