ABOVE ALL, DO NOT PLUG THE TEMPERATURE AND PRESSURE RELIEF VALVE. THIS IS NOT A SOLUTION AND CAN CREATE A HAZARDOUS SITUATION.

CIRCULATING PUMP

The water heating system may include a circulating pump. Where used, it should be lubricated as directed by the circulator manufacturer.

LOW EMISSION POWER BURNER

KEEP THE AREA AROUND THE BURNER CLEAR AND FREE OF COMBUSTIBLE MATERIALS, GASOLINE OR OTHER FLAMMABLE LIQUIDS OR VAPORS. DO NOT OBSTRUCT BURNER AIR OPENINGS OR VENTILATION GRILLES FOR COMBUSTION AIR. REMOVE LINT ACCUMULATION FROM AIR INTAKE GRILL.

The main burner flame should be visually checked once a year for proper operation. This can be observed through the “peep sight” port on the burner mounting plate. Burner flame should be kept blue.

At least annually, contact a qualified service agency for burner cleaning and other routine maintenance. For burner related Maintenance Schedule, Troubleshooting, Flame Rod, Ignitor, Thermal Cut-Off Switch Replacement Procedures, use burner Operation & Maintenance Manual provided with this heater.

CLEANING FLUES

The following describes how to gain access to the tank flues for cleaning if necessary.

1.Turn off the heater electrical disconnect switch.

2.Remove the vent connector from on top of the heater.

3.Remove the jacket top from the heater by taking out the screws and lifting it off.

4.Remove the insulation from the top of the heater.

5.Remove the inner cover by taking out the pipe collar around the water inlet and outlet nipple.

6.The flue baffles may now be removed by lifting out.

7.Using a wire brush, a nylon brush must not be used, remove soot from flue passages in heater tank.

CAUTION

While cleaning tank flue passages, care must be taken that brush does not come in contact with neither the combustion chamber lining nor the baffle or funnel which are an integral part of the combustion chamber, as damage could occur. The flue passages are 48-1/2” (1,232 mm) long x 3” (76.2 mm) diameter.

8.Upon completion of cleaning, return heater to operation by following this procedure in reverse.

BAROMETRIC DRAFT CONTROL

- FOR GPG MODELS

The heater is equipped with a double acting barometric draft control as shown in Figure 15. The damper gate must pivot freely in the ring guides.

FIGURE 15

To test gate for operation, gently tap gate and observe. DO NOT OIL.

Adjust the number of counter-weight washers on the control to maintain a negative draft of 0.02” to 0.04” w.c. in the venting. See VERTICAL VENTING, page 8.

NOTE THAT THIS CONTROL WILL ONLY BE PRESENT IN A VERTICAL VENT INSTALLATION.

VENT SYSTEM

Examine the vent system every 3 months. Points of inspection are as follows:

1.Check for obstructions and/or deterioration of vent piping and vent hood. Replace immediately where needed.

2.Vent pipe and vent hood screen should be cleaned of foreign material and soot. The screen is located inside the vent hood outlet and is accessible from the outside of the hood. Do not reach inside the vent when the heater is in operation.

3.Check all vent system connections for leakage and re-seal as required using Hi Temp Silicone sealer or equivalent.
