Thomas & Betts RZ405, RGM 405 Check installation after start-up, To Turn OFF GAS to the Appliance

TO TURN OFF GAS TO THE APPLIANCE

1)Set thermostat to lowest setting

2)If service is to be performed, turn off all electric power to the appliance.

3)Open the access door.

4)Turn the gas control knob to "OFF" (follow instruc- tions in No. 4 above). Do not force control knob.

5)Close the access door.

Check installation after start-up:

%&Vent System Testing Procedure - Power Vent Units (does not apply to separated-combustion installation)

1.Seal any unused openings in the venting system.

2.Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI Z223.1 or CAN/CGA B149.1 and B149.2, Installation Code for Gas Burning Appliances and Equipment, and this manual. Determine that there is no blockage or restric- tion, leakage, corrosion and other deficiencies which could cause an unsafe condition.

3.In so far as practical, close all building doors and win- dows and all doors between the space where the heater is and other spaces of the building. Turn on clothes dryers and exhaust fans, such as range hoods and bathroom exhausts, so they shall operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.

4.Light the heater following the lighting instructions. Ad- just the thermostat for continued operation. Verify that combustion products are venting properly. After deter- mining that the heater vents properly, return doors, win- dows, exhaust fans, and fireplace dampers to their previ- ous conditions. If improper venting is observed, the vent- ing system must be corrected.

%With the unit in operation, measure manifold gas pressure. Manifold pressure for natural gas should be 3.5" w.c. and 10" w.c. for propane gas. See Paragraph 9.

%Turn the unit off and on, pausing two minutes between each cycle. Observe for smooth ignition.

%Place the "Owner's Envelope" containing the Limited War- ranty, this booklet, the operation/maintenance/service manual, and any control or optional information in an accessible loca- tion near the heater. Follow the instructions on the envelope.

DANGER: The gas burner in this gas-fired equipment is designed and equipped to provide safe and economically controlled complete combustion. However, if the installation does not permit the burner to receive the proper supply of combustion air, complete combustion may not occur. The result is incomplete combustion which produces carbon monoxide, a poisonous gas that can cause death. Safe operation of indirect-fired gas burning equipment requires a properly operating vent system which vents all flue products to the outside atmosphere. FAILURE TO PROVIDE PROPER VENTING WILL RESULT IN A HEALTH HAZARD WHICH COULD CAUSE SERIOUS PERSONAL INJURY OR DEATH.

If installed as a separated-combustion unit, install either the horizontal or vertical combustion air/ vent system illustrated in Paragraph 7A using the concentric adapter supplied. Always comply with the combustion air requirements in the installation codes and instructions. Combustion air at the burner should be regulated only by manufacturer- provided equipment. NEVER RESTRICT OR OTHERWISE ALTER THE SUPPLY OF COMBUSTION AIR TO ANY HEATER. CHECK THE VENT SYSTEM FOR SOUNDNESS AND FUNCTION; MAINTAIN IT IN PROPER OPERATING CONDITION.
