CONSULTING RAYPAK, AS ANY DAMAGE  
1.  
Read these instructions in full !  
Where A = Minimum free ventilation area (cm2)  
T = Total hourly input of all appliances (Mj/h)  
OR FAULTS CAUSED BY UNAUTHORISED  
START UP MAY NOT BE COVERED BY  
OUR WARRANTY.  
2.  
Check that the heater you have  
been supplied is suitable for the type of  
installation and the gas available. The gas  
supply pressure must be between the  
minimum and maximum shown on the  
heater data plate.  
Note: The minimum dimension of any opening  
shall be 6mm.  
HEATER LOCATION AND  
CLEARANCES  
Please take the heater location into account  
when locating the fresh air vents because any  
excessive draft will cause flame disturbance  
and probable pilot outage. In some cases  
where excessive draft effects the burner, the  
risk of major damage is high due to  
The heater should be located so that any  
possible water leaks will not cause damage to  
any adjacent areas or structures.  
GENERAL  
These instructions are provided to ensure the  
correct installation and operation of your  
Raypak Swimming Pool Heater.  
When such locations cannot be avoided, it is  
recommended that a suitable drain pan,  
adequately drained, be installed under the heater.  
incomplete combustion.  
Installations which obtain air from a source  
other than directly from outside must comply  
to AG601.  
Should any questions arise regarding the  
specifications, installation, operation or  
servicing of this heater, we suggest that the  
local representative or Raypak Customer  
Service be consulted.  
This pan must not restrict combustion air flow.  
The heater must be mounted on a level non-  
combustible base such as a concrete slab,  
concrete plinth, steel plate etc.  
Warning: Air supply to the heater room  
must not be affected by mechanical  
exhaust vents located in other parts of  
the house or building, such as kitchen or  
bathroom fans, spa blowers, etc.  
Raypak heaters utilise a finned copper tube  
heat exchanger resulting in a low water content  
and reduced "stand by" heat losses. Therefore  
a circulator pump of sufficient capacity to  
match the heater model must be installed in  
the system.  
Raypak heaters and equipment must not be  
installed on carpeting.  
The front of the heater must not be obstructed  
by any gas or water piping, electrical conduits,  
trees, fences, or other equipment, etc.  
Mechanical exhaust vents may create a negative  
pressure in the heater room that can become a  
hazard by asphyxiation, explosion or fire.  
Raypak heaters are fitted with Australian Gas  
Association approved components and all  
boilers in this range are designed to comply  
to AG501.  
Caution: Do not store chemicals or flammable  
materials in the same room or near this  
heater. Do not use aerosols near this heater  
whilst it is in operation.  
Some models are designed for either indoor or  
outdoor installation subject to the appropriate  
indoor draft hood or outdoor stackless top  
being fitted.  
FLUEING  
The correct Draft hood must be fixed to the top  
of the heater and connected to a properly  
constructed flue, vented to the outside using  
only approved fittings.  
Check that the correct top for your installation  
has been supplied.  
Reduction of the flue diameter or alteration to  
the draft hood voids all warranty. Where  
INSTALLATION PROCEDURES  
flueing may be difficult, please contact Raypak  
for advice, we will have solutions, particularly  
where a fan assisted flue may be the answer.  
All electrical, gas piping, gas connection and  
flueing of the heater must only be undertaken  
by a properly authorised person. The  
installation must comply with local gas, AG601-  
2000 and electrical codes and/or statutory  
body codes and regulations.  
COMBUSTION/VENTILATION  
AIR  
The weight of the flue must not rest on the  
heater draft diverter, the flue must be self  
supporting and be fitted with a disconnection  
section (bolted sleeve) to enable the heater top  
and draft diverter to be removed easily, for  
servicing. Where practicable the flue should run  
vertically. Lateral (raised above horizontal) is  
acceptable but the run of a flue shall not  
exceed 50% of total flue height and shall be  
designed to rise not less than 20 mm per 1 m  
run. The flue must be terminated with an  
approved cowl.  
Indoor model heaters must only be installed in  
a protective enclosure or properly constructed  
plant room with adequate ventilation in  
accordance with AG 601 - 2000 Gas  
Installation Code.  
Raypak heaters must be installed in the  
filtration system, in the pool return line,  
downstream from the filter.  
Ventilation shall be via 2 permanent openings  
directly to outside, one at an upper level and  
one at low level.  
INSPECTION OF EQUIPMENT  
Check the heater and associated equipment for any  
damage and if so notify your local representative or  
Raypak for any further instructions.  
The minimum free area provided by each vent  
shall be as calculated by using the following  
formula, unless otherwise stated in AG 601.

PART 2 - SECTION I - INSTALLATION INSTRUCTIONS  
Raypak recommends a minimum length of  
vertical flue of three (3) metres to ensure  
correct draft.  
HIGH WIND CONDITIONS  
Caution: The gas supply must be isolated from  
the heater during pressure testing of the gas  
fitting line.  
On rare occasions or in areas where high  
winds frequently occur, it may be necessary to  
locate the heater a minimum of one (1) metre  
from high vertical walls, or install a wind break  
so that the heater is not in direct wind current.  
Dissipate test pressure before reconnecting to  
the heater.  
AGA Approved Cowl  
Failure to follow this procedure may result  
in damage to the gas valve. (Over  
pressured valves and equipment are not  
covered by our warranty.)  
Distance above roof must be  
Models 538 to 1852, where the installation  
may cause "Down draft", Raypak can supply a  
Wind Deflection Plate (at extra cost), to  
eliminate constant ignition failures or flame  
disturbance, the need for which would be  
determined by an approved Raypak Service  
Person or Agent.

WATER CONNECTIONS AND  
SYSTEM PIPING  
The heater must be installed to the appropriate  
and/or local codes. For typical piping systems  
and heater applications it is essential that  
Raypak be consulted, Raypak heaters do have  
some special requirements and if you are not  
familiar with Raypak products we can save you  
unnecessary inconvenience!

Water pipe connections to heater are:  
OUTDOOR INSTALLATIONS.  
In areas of "constant extreme winds" or where  
a Wind Deflection Plate is not appropriate, it  
may be necessary to replace the "standard"  
low profile outdoor hood with a HIGH WIND TOP  
which would be at extra cost.  
538 to 1292 - 50 mm copper slip fit or 2" NPT,  
1362 to 1922 - 80mm BSP and  
2004 to 4224 - 100 mm BSP.  
An outdoor heater must not be installed inside  
any roofed structure or under eaves, roof  
overhangs, or pool decks. It should also be at  
least 1500 mm, in any direction from any  
window or fresh air opening.  
Do not reduce the pipework size and heater  
water connections without allowing for any  
friction loss which will occur. Low water flow  
will cause damage to the heater and system  
components. Please install pipework using  
approved fittings and isolating valves that will  
allow easy disconnection for any future  
maintenance requirements.  
The HIGH WIND TOP serves the same function  
as the low profile outdoor hood and should be  
installed in accordance with the same  
clearance requirements.  
When installing the heater on a raised base,  
please make sure that the base material is  
solid and filled in. E.G. If steel mesh decking is  
used, a suitable plate material must be used to  
fill in the perforations. This is very important, as  
any excessive drafts must not be able to enter  
the unit from directly underneath.

GAS SUPPLY  
Elevated Deck  
The gas supply pipe must be sized to give  
sufficient pressure for the correct operation  
of the heater. The gas line must be fitted  
with an isolation valve. Consult AG 601 for  
further details.  
NEVER CONNECT LOW TEMPERATURE PVC  
PRESSURE PIPE DIRECTLY TO THE HEATER.  
A non-return valve must be installed on the  
inlet side of the heater, after the filter.

PART 2 - SECTION I - INSTALLATION INSTRUCTIONS  
PUMP SELECTION  
The filtration pump must be sized to provide an  
adequate water flow for the filtration system  
and the heater. In some cases however, this  
can cause a high back pressure which reduces  
the filtration capacity and in this case it would  
be more of on advantage to install an additional  
pump for the heater only. This pump must be  
installed on the inlet side.  
DO NOT connect the pump to the heater outlet.  
Some heater models incorporate their own By-  
Pass Pump but this is used to control the  
temperature of the water entering the heater to  
prevent condensation and scale and will not be  
suitable as the additional pump described above.  
Refer to the Flow Rate chart following when  
sizing the pump.  
Where the water flow rate exceeds the  
maximum shown in the chart, a by pass valve  
must be installed to reduce the water flow  
through the heater.  
A pump run on timer must be fitted to remove  
any residual heat from the boiler and prevent  
any nuisance tripping of the high limit switch.

COMMISSIONING  
11. Check that the gas supply is isolated and  
with the main gas valve isolation switch turned  
off, check the boiler gas train and components  
for gas escapes.  
The digital display on the electronic thermostat  
will indicate the pool water temperature.  
WARNING: COMMISSIONING MUST ONLY BE  
UNDERTAKEN BY A PROPERLY AUTHORISED  
AND IN SOME CASES APPROPRIATELY  
LICENSED PERSON WHO IS FAMILIAR WITH  
SAFE COMMISSIONING PROCEDURES. THE  
COMMISSIONING MAY REQUIRE  
17. Check that the flue is operating correctly  
or if there is evidence of Down draft etc report  
as necessary.  
12. Start the circulation pump and verify the  
pressure switch operation, then test the  
operation of the heater with no gas flow to  
confirm its operation up to the lockout status.  
Pressure switch adjustment is required if the  
unit won’t fire and after faultfinding it is verified  
that the pressure switch has not closed.  
Adjust the pressure setting at the thumbwheel  
to a lower setting, then re start the heater.  
If the heater fires up but won’t shutdown when  
the water is reduced then it will require  
adjustment to the thumbwheel to a  
18. Check operation of any water pressure  
relief valves etc and set up the controls to  
desired settings.  
INSPECTION BY THE GAS SUPPLY  
AUTHORITY, CHECK IF THIS IS APPLICABLE.  
19. Ensure that the customer is supplied with  
this manual and you have demonstrated the  
operation of the unit etc.  
RECOMMENDED  
COMMISSIONING PROCEDURE.  
It is quite normal for the heater to produce  
some smoke and possible condensation for the  
first thirty (30) minutes of firing from new.  
1. Check that all necessary approvals and  
appropriate documents have been obtained.  
2. Ensure that the heater is clean and the  
surrounding area is clear of all combustible and  
flammable materials.  
WARNING - Should overheating occur or the  
gas fail to shut off, turn off the gas isolation  
valve adjacent to the heater and then  
higher setting and the heater restarted.  
(In some cases the electrical interlock between  
the pump and heater may require a temporary  
disconnection to carry out tests.)  
3. Remove all liquids and chemicals from the  
plant room and check that combustion air  
openings are not obstructed. Chemicals must not  
be stored in the plant room - this is extremely  
dangerous and may damage the heater.  
examine the unit or call for assistance.  
13. Open the gas supply valve, switch on the  
main valve isolation switch and reset the  
ignition control to fire the heater.  
4. Fill the system with water and expel any air  
as required.  
14. When the unit fires and reaches high fire,  
set the burner gas pressure to that shown on  
the data plate which is located on  
the front of the heater.  
5. Purge all air from gas supply piping.  
CAUTION: Liquid Propane Gas is heavier than  
air and sinks to the ground, exercise extreme  
care in lighting boiler in confined areas.  
15. Verify that the high limit and any other  
safety devices are operating correctly.  
16. Check the water temperature rise of the  
heater and adjust the water flow as necessary.  
For models 538-1292, measure the  
temperature difference between the Inlet and  
Outlet pipes at the heater, with the unit at full  
fire.  
The difference should be approximately 5 - 10  
Deg. C.  
If it is lower than recommended, decrease the  
water flow through the heater.  
6. Test ALL gas connections for leaks, using  
soapy water and a manometer.  
(NOT A NAKED FLAME)  
7. Conduct a visual inspection of the heater  
and equipment for any damage or installation  
problems and report as necessary.  
8. Check that the correct power supply is  
available and the circulation pump is  
electrically interlocked with the heater.  
If it is higher than recommended it indicates  
that the water flow rate is too low.  
For models 1362 to 4224, the temperature  
gauges which are fitted to the heater can be  
used as a guide.  
The objective is to maintain a temperature of  
approximately 50 Deg C at the outlet side of  
the heater, 30 Deg C at the inlet side, with the  
unit at full fire.  
9. Check that the ventilation to the plant room  
complies with Raypak requirements, AG601  
and local authority regulations.  
If mechanical ventilation is provided, check its  
operation and any interlocks.  
10. Check that the flue complies with the  
appropriate regulations and is fitted with an  
approved termination cowl.
