4.As the appliance comes on and fires, record the inches of water column of displacement on both sides of the manometer. The sum of these two readings as they are effected by the two air pressures is the differential air pressure.

5.

The differential air pressure should be 3.5 inches

 

of water column (+ 0.1” w.c.) when the burner is

 

firing at 100% of rated input.

6.If the differential air pressure is not 3.5 inches water column (+ 0.1” w.c.), review the installation. Check for proper installation of the venting system. Review the venting requirements in this manual for the specific venting system installed with this appliance. Correct as required. Ensure that an adequate supply of combustion air is supplied to the appliance. If a separate pipe is used to supply combustion air, ensure that it is installed per the combustion air pipe requirements contained in the venting section of this manual. Correct as required. Check the air inlet screen to the combustion air blower. Clean as required. Check the burner for dirt or contamination and clean as required. Recheck for correct differential air pressure after correcting an installation related problem or after cleaning an obstructed component. Ensure that a combustion air differential of 3.5 inches water column (+ 0.1” w.c.)

is present while the appliance is firing at 100% of rated input.

7.This is a reference pressure only and is not field adjustable. An appliance supplied with an unrestricted supply of combustion air from a correctly sized combustion air opening or separate direct vent combustion air pipe will operate at the correct air pressure differential as the burner input varies with temperature demand.

8.Close the two air pressure test cocks on the pressure test tree and remove the hoses to the manometer.

9.Close the front control panel.

L. COMBUSTIBLE MATERIALS

CAUTION￿

Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

FREEZE PROTECTION

Installations are not recommended in areas where the danger of freezing exists. Proper freeze protection must be provided for appliances installed in unheated mechanical rooms or where temperatures may drop to the freezing point or lower. If freeze protection is not provided for the system, a low ambient temperature alarm is recommended for the mechanical room. Damage to the appliance by freezing is non-warrantable.

1.Pump Operation - MOST IMPORTANT - This appliance is designed for continuous pump operation when the burners are firing. The integral circulating pump will run continuously when the power switch is in the “ON” position and the run/stop switch is in the “RUN” position. As an optional feature an intermittent pump control system can be provided. The intermittent pump option allows the integral circulating system pump to be cycled on at each call for heat and cycled off when the set point is satisfied. The intermittent pump will operate for a timed period after the burner cycles off to remove residual heat from the combustion chamber area. If the operating temperature sensor for an intermittent pump system sees a drop in water temperature to 45°F (7.2°C), the integral circulating pump will cycle on. This flow of warm boiler water can help prevent freezing.

2.Location - Heating boilers, hot water supply boilers

or water heaters must be located in a room having a temperature safely above freezing [32°F(0°C)].

3.Caution - A mechanical room operating under a negative pressure may experience a downdraft in the flue of an appliance that is not firing. The cold

outside air may be pulled down the flue and freeze a heat exchanger. This condition must be corrected to provide adequate freeze protection.

4.A motor driven damper may be installed in the air inlet to prevent cold air movement in cold climates. The damper MUST be interlocked with boiler/water heater controls to open and prove on a call for heat.

5.Freeze protection for a heating boiler or hot water supply boiler using an indirect coil can be provided by using hydronic system antifreeze. Follow the manufacturers instructions. DO NOT use undiluted or automotive type antifreeze.

6.Shut-down and Draining - If for any reason, the unit is to be shut off, the following precautionary measures must be taken:

(a)Shut off gas supply.

(b)Shut off water supply.

(c)Shut off electrical supply.
