PVI Industries PV500-2 manual Start-Upprocedures And Operation

START-UP PROCEDURES AND OPERATION

1.Some PVI atmospheric gas-fired water heaters are designed to operate with a flue damper that is shipped with the water heater for installation in the field. If your water heater was shipped with a flue damper, it must be attached to the flue collector and interconnected to the ignition control module before proceeding with start-up.

Flue Damper Installation

a.Set the flue damper over the flue collector opening and align the damper drive housing to the front of the heater.

b.Secure the flue damper to the flue collector at three locations using the fasteners provided.

c.Remove the damper drive housing cover, feed the damper interconnect cable through the access hole and attach the female connector to the four-pin receptacle. Secure the access hole cover, check to make sure the test switch is in the "NORMAL" position, and reattach the damper driver housing cover.

CAUTION: BE SURE THERE IS NO FOREIGN MATTER IN THE DAMPER HOUSING BEFORE ATTACHING THE DRAFT DIVERTER.

Draft Diverter Installation

The draft diverter (provided) is designed to mount on top of the flue damper. Set the draft diverter on top of the flue damper and secure in three locations using the fasteners provided.

Venting

Type B galvanized vent pipe, of the same diameter as the draft diverter outlet, must be installed to route combustion products either to existing overhead breeching or to an appropriate outside location.

1.The control manufacturer's installation and service manual and start-up procedures for the control system on your water heater are shipped with the unit. Study the information carefully and follow the manufacturer's recommendations.

2.Fill the water heater tank with water. Open the relief valve or a nearby hot water faucet to allow air in the tank to escape. Be sure all connections into the tank are tight as leaks at tank fittings will damage the insulation.

3.Remove the control box cover to access the control thermostats and other electrical devices needed to operate the water heater. The thermostats are labeled as to their function. The temperature limiting device is set at 200°F. The thermostats are factory set at 130°F. (the upper operating thermostat) and 120°F (the operating thermostat). Adjustment may be made by turning the thermostat dial to the desired temperature.

CAUTION: BE SURE TO REATTACH THE CONTROL BOX COVER TO HELP PREVENT UNAUTHORIZED ACCESS TO CONTROLS.

CAUTION: DO NOT OVERTIGHTEN COMPRESSION FITTINGS ON THERMOSTAT BULBS AS CALIBRATION WILL BE CHANGED.

CAUTION: TEMPERATURES HIGHER THAN 125°F INCREASE THE RISK OF SCALD INJURY!
