AFTER START-UP  
SECTION 2 / CAUTION  
Elevated water temperature can be hazardous,  
and the U.S. Consumer Product Safety Commission  
recommends the following guidelines:  
Feel the inlet and outlet pipes. Outlet pipe should be  
only slightly warmer than the inlet. It should not be hot.  
WARNING: Should overheating occur or the gas sup-  
ply failtoshutoff, turnoffthemanualgascontrol valve  
to the appliance.  
1. Spa or hot tub water temperatures should never  
exceed 104°F (40°C). A temperature of 100°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 subse-  
quently result in drowning.  
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).  
Pregnant women should stick to the 100°F  
(38°C) maximum rule.  
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  
pattern.  
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  
four degrees Fahrenheit (2.2°C).  
5. Persons with a medical history of heart disease,  
circulatory problems, diabetes, or blood pres  
sure problems should obtain a physician's  
advice before using pools or hot tubs.  
MAIN BURNER FLAME  
6. Persons taking medications which induce  
drowsiness, such as tranquilizers, antihista  
mines, or anticoagulants, should not use spas or  
hot tubs.  
SECTION 3 / MAINTENANCE  
AND CARE PROCEDURES  
To be followed one month after start-up and then  
semi-annually.  
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.  
1. Inspect top of heater and draft hood for soot, (a  
sticky black substance around finned tubes,  
baffle and open flue gas passageways).  
WATER PRESSURE SWITCH  
A water pressure switch is provided in the heater to  
shutofftheburnersin theeventthatwatersupplytothe  
heater is interrupted. It is very important to verify that  
the switch electrically opens and shuts off the gas  
valve when water flow to the heater is interrupted.  
Otherwise, rapidandseveredamagewilllikelyoccurto  
the heater. (The water pressure switch should be  
checked and adjusted for proper operation by a quali-  
fied service person at the time of installation and  
periodically checked thereafter. Refer to pressure  
switchservicinginstructioninSection4ofthismanual.)  
CAUTION: Soot may be combustible. Wet sooted  
surfaces completely prior to cleaning. Do not use  
steel wire brush.  
2. Clean main burners and pilot burner of dust and  
lint.  
3. Inspect and operate all controls, gas valve and  
pressure relief valve.  
WARNING: Operation of the heater without water  
circulation will cause rapid and severe damage to the  
heater.

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.  
POOL & SPA WATER CHEMISTRY  
Chemical imbalance can cause severe damage to  
your heater and associated equipment. Maintain your  
water pH between 7.4 and 7.8 and total alkalinity  
between 100 and 150 p.p.m. If the mineral content and  
dissolved solids in the water become too high, scale  
forms inside the heat exchanger tubes, reducing  
heater efficiency and also damaging the heater. If the  
pH drops below 7.2, the heater will be severely dam-  
aged. This will result in corrosion of the heat ex-  
changer. Heat exchanger damage resulting from  
chemical imbalance is not covered by the war-  
ranty.  
5. On indoor heaters, clean room intake openings  
to assure adequate flow of combustion and  
ventilation air.  
CAUTION: Combustion air must not be contaminated  
by corrosive chemical fumes which can damage the  
heater and void the warranty.  
COLD WEATHER OPERATION  
MODERATE CLIMATE: Heater operation can con-  
tinue during short term cold spells. When tempera-  
tures are below freezing, flow (continuous pump op-  
eration) must be maintained.  
6. Keep area around heater clear and free from  
combustible materials and other flammable and  
corrosive vapors and liquids.  
CAUTION: Do not use the heater to maintain water  
temperatures just above freezing or for freeze protec-  
tion. When heaters are used during freezing weather  
care must be taken to avoid freeze ups. Continuous  
pump operation is a must. Additional protection may  
be required. The heater is not warranted against  
freeze ups.  
BASIC TIPS IF HEATER WILL NOT FIRE:  
1. If you have no electrical power; it may be your  
"circuit breakers" have tripped. Try re-setting  
them.  
2. If you have electrical power but the heater will  
not fire  
COLD CLIMATE: Prolonged operation with water  
temperatures below 50°F is not recommended. When  
starting the heater with pool temperatures below 50°F,  
operate the heater continuously until higher tempera-  
tures are reached. Operating the heater for prolonged  
periods with pool water below 50° can seriously dam-  
age the heater, and is not covered by the warranty.  
check the following:  
3. The time clock must be moved to the "ON"  
position.  
4. Your pump strainer basket may be full. If so  
remove debris.  
For cold climate areas please follow the winterizing  
procedures listed below.  
5. Your filter may be dirty. If so, backwash or  
clean filter.  
WINTERIZING THE SPA HEATER  
(To tell if your filter is dirty, the gauge pressure  
will be higher than usual).  
When heaters installed outdoors in freezing cli-  
mate areas are to be shut down for the winter, observe  
the following step-by-step procedure:  
6. The pump may have lost it's prime. It may be  
running dry, check the pressure gauge on the  
filter. If there is no pressure; then you are not  
moving water (or your gauge is broken). Try to  
get the pump to run at it's normal flow rate.  
1. Turn off gas valve, manual gas valve, and electri-  
cal supply to the heater.  
2. Open drain cock located on the return header.  
3. Disconnectcompressionfittingsfromthepressure  
switch and header that connect to the 1/4"  
copper tube and allow the tube to drain.

PLUMBING FOR WATER CONNECTIONS  
LOCATION  
CAUTION:NeverinstallPVCdirectlyinheaderflanges.  
The VERSA heater requires water flow and posi-  
The initial connection must be made with a higher  
tive pressure to fire and operate properly. It must temperature material such as CPVC or Copper. PVC  
therefore be installed downstream of the discharge  
side of the filter pump. A typical installation is plumbed  
as follows:  
may be utilized immediately after the initial connection.  
AUTOMATIC CHLORINATORS AND CHEMICAL  
FEEDERS  
1. The inlet side of the filter is plumbed directly  
to the discharge side of the filter pump:  
2. The outlet side of the filter is then plumbed  
to the inlet of the heater; and  
3. The outlet of the heater is plumbed to the  
return line to the spa. The pump, filter and  
heater are thus plumbed in series.  
All chemicals must be introduced and completely  
dilutedintothepoolorspawaterbeforebeingcirculated  
through the heater. Do not place chlorine tablets or  
bromine sticks in the skimmer. High chemical concen-  
trations will result when the pump is not running (i.e.  
overnight).  
Plumbing from the heater back to the spa must not  
have any valves or restriction that could prevent flow  
when the pump is operating. To do so will void the  
warranty.  
Chlorinators must feed downstream of the heater  
and have an anti-siphoning device to prevent chemical  
back-up into the heater when the pump is shut off.  
NOTE: High chemical concentration from feeders and  
chlorinators that are out of adjustment will cause very  
rapid corrosion to the heat exchanger in the heaters.  
Such damage is not covered under the warranty.  
Heatermustbelocatedsothatanywaterleakswill  
not damage the structure of adjacent area. High  
temperature plastic pipe (CPVC) may be connected  
directly into the heater if local codes permit.  
UNITHERM GOVERNOR OPERATION  
FLOW RATES  
PIPE SIZE: 1 1/4"-1 1/2" MIN.GPM: 20, MAX.GPM: 60*  
The patented Unitherm Governor is a thermostatic  
mixing valve specifically designed to maintain constant  
heater internal temperature between 105° - 115°F de-  
spite continually changing flow rates from the filter and  
changing pool temperatures. This narrow range is  
neededtopreventdamagingcondensationontheburn-  
ers which will occur if the heater runs for any length of  
time below 100°F. It is also needed to inhibit scale  
formationinthetubesbymaintainingtemperatureswell  
below accelerated scaling temperatures.  
*When flow rates exceed 60 GPM an external auxil-  
iary bypass valve is required. See External auxiliary  
bypass valve section for details.  
COMPANION FLANGE CONNECTIONS  
The inlet/outlet header flange accepts a 1 1/2"  
copper tube or 1 1/4" galvanized pipe as a slip connec-  
tion directly into the manifold. The flange is also  
threaded for 1 1/2" pipe thread. 1-1/2" CPVC adapters  
(when available) can also be used.  
DO NOT use petroleum base assembly fluids  
(such as Petroleum Jelly or lubricating oil). If assembly  
lube is required, use a silicone base compound, such  
as Amoral, etc.

(Where required)  
throughout its entire length and must pitch downward  
from the valve. No shut-off valve shall be installed  
between the relief valve and the drain line. Valve lever  
should be tripped at least once a year to ensure that  
waterways are clear.  
An auxiliary bypass valve should be used when  
flowratesexceed60GPM(usuallyahighperformance  
pump size larger than 1 1/2 HP will exceed this flow  
rate).Thisvalveisrequiredtocomplementthe function  
of the automatic bypass valve, particularly when start-  
ing the heater in winter or early spring when the spa or  
pool temperature is down below 55°F. It also serves to  
eliminate needless pressure drop through the heater  
and accompanying reduction in the flow rate to the spa  
jets, etcetera.  
ELECTRICAL WIRING  
NOTE: If it is necessary to replace any of the original  
wiring, it must be replaced with 105 °C wire or its  
equivalent, except all black wire must be replaced with  
150 °C wire or its equivalent.

NOTE: When the electrical hookup to the heater  
requires both 24V and 115V or 240V, each input  
voltage must be isolated in separate conduit.  
Fig. # 8150.0s  
AUXILIARY BYPASS VALVE ADJUSTMENT  
To set bypass: With clean filter, adjustment is  
madeby feelingtheinletandoutletpipesattheheater.  
Outlet pipes should be slightly warmer than inlet and  
comfortable to the touch. If pipe is hot, close bypass; if  
cold, open bypass  
The Electronic Intermittent Ignition Device auto-  
matically lights the pilot and main burners upon a call  
for the heat. The heater is supplied with a dual voltage  
transformer for 120V or 240V input power hookup.  
NOTE: IID Propane Units Only  
PRESSURE RELIEF VALVE INSTALLATION  
To conform to local building codes, it may be  
necessary to install a pressure relief valve. A 3/4"  
pressure relief valve having a capacity equal to BTU/  
HR output of the model to be installed is recommended  
for this appliance.  
Heater is equipped with an electronic ignition device  
with a 100% safety lockout feature. If the heater fails  
to start or lockout. Reset the ignition device by inter-  
rupting the power to the heater for 60 seconds.  
CAUTION: If service replacement of the electronic  
ignition device is required. Replace only with a 100%  
safety lockout device with 90 second trial for pilot  
ignition.
