   Installation and Operation Manual

held beneath the burners. The flame should be

 

a.  Blue in color.

 

b.  1 to 4 inches (25mm to 102mm) above 

burner surface. See Figure 23.

7.  Inspect the gas and electronic controls, including 

the following:

 

a.  High temperature limit switch

 

b.  Water pressure switch

 

c.  Automatic gas valve

 

d.  Fusible Link

 

e.  Temperature control

 

f. 

Vent fusible link

8.  Perform a temperature rise test in accordance 

with Section 7.6.

9.  If the heater is equipped with a pressure relief 

valve, check for corrosion in and around the 

valve. With the filter pump on, lift the release 

lever on the top of the valve to make sure that 

water runs freely through it. If corrosion is found, 

replace the pressure relief valve. When replacing 

the valve, be sure that the pump is off. Install the 

valve so that the discharge is directed away from 

any area that may be damaged by water.

10.  Inspect the external surfaces of the heat exchang-

er tubes for black carbon soot buildup by placing 

a mirror between and under the burners when the 

heater is firing. Remove any soot that has collect-

ed on the tubes, and correct the cause.

Note

  After installation and first start-up, check the 

heat exchanger for black carbon soot buildup 

after the following periods of operation: 24 

hours, 7 days, 30 days, 90 days, and once 

every 6 months thereafter.

 

WaRNiNG

Do not use this heater if any part has been under 

water. Immediately call a qualified service techni-

cian to inspect the heater and replace any part of 

the control system and any gas control which has 

been under water.

N'utilisez pas cet appareil s'il a été plongé dans 

l'eau, même partiellement. Faites inspecter 

l'appareil par un technicien qualifié et remplacez 

toute partie du système de contrôle et toute com-

mande qui ont été plongés dans l'eau.

3.  If the heater is equipped with a pressure relief 

valve, check for corrosion in and around the 

valve. Twice a year, with the filter pump on, lift 

the release lever on the top of the valve to make 

sure that water runs freely through it. If corrosion 

is found, replace the pressure relief valve. When 

replacing the valve, be sure that the pump is off. 

Install the valve so that the discharge is directed 

away from any area that may be damaged by 

water. 

4.  Be sure all combustion air and ventilation 

openings are not blocked. Check for spider webs 

and other debris inside the heater, in the vents on 

all sides of the heater jacket and in the exhaust 

outlet– especially after a long period of nonuse.

8.3.2  Professional inspection

Inspections performed at least once a year by 

a qualified technician are required to maintain your 

heater's safe and efficient operation. The following 

basic safety checks must be performed.
1.  Inspect the venting system for blockage, leakage, 

and corrosion.

2.  Inspect burners and verify that they are clean. 

Clean with a wire brush if necessary to remove 

debris.

3.  Check for spider webs and other debris in the 

pilot and main burner orifices - especially at 

spring start-up.

4.  Check for loose or broken wires and terminal 

connections.

5.  Make sure that the pressure switch operates 

properly by shutting the filter pump off and on 

a few times. The burner should go off immedi-

ately after the pump stops. An ignition sequence 

should start shortly after the pump is turned back 

on.

6.  Make a visual check of the main burner flame. 

The flame can be seen in a mirror arrangement
