(d)Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so appliance will operate continuously.

(e)Test for spillage at the drafthood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle, or smoke from a cigarette, cigar or pipe.

(f)After it has been determined that each appliance remaining connected to the common venting sys- tem is venting properly, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their previous conditions of use.

(g)Any improper operation of the common venting system should be corrected so that the installation conforms with the latest edition of the National Fuel Gas Code, ANSI Z223.1. When re-sizing any portion of the common venting system, the com- mon venting system should be re-sized to approach the minimum size as determined using the appropriate tables in Part 11 of the National Fuel Gas Code, ANSI Z223.1.

For special venting applications that require reduced vent sizes and through-the-wall venting, the Type D Induced Draft Assembly can be used. Consult the factory or your local Raypak representative.

VENT DAMPER INSTALLATION

MODELS 133 THROUGH 261 (WHERE REQUIRED)

LOCATION

The vent damper must be located in the vent so that it serves only the appliance for which it is intended.

If improperly installed, a hazardous condition, such as an explosion or carbon monoxide poisoning, could result. Make certain that it is mounted in an accessible location at least 6 in. from any combustible material or the heat exchanger and that the position indicator is in a visible location.

The vent damper must be installed after the appli-

ance drafthood, as close to the drafthood as practi-Fig. # 8182.0 cable, and without modification of the drafthood.

WARNING: Do not use thermally actuated vent dampers on modulating heater. To do so, may result in asphyxiation. Use only a mechanically actuated vent damper device that is electrically interlocked with the modulating heater operation.

MOUNTING

On vertical vents, the vent damper may be mounted with the actuator in any position. On horizontal vents, do not mount the actuator either directly above or directly below the vent pipe; mount the vent damper actuator to the side of the vent.

The vent damper is set up for a continuous pilot system. If the vent damper is installed on an Intermittent Pilot or Direct Spark Ignition equipped system, the energy savings of the vent damper can be improved by plugging the hole in the vent damper blade using the knockout plug, Part No. 105612R, provided in the parts envelope.

DO NOT plug the hole if installing the vent damper on a continuous pilot system as this will create a hazardous condition.
