GIDM INDUSTRIAL / COMMERCIAL PACKAGED FURNACES INSTALLATION, OPERATION AND MAINTENANCE MANUAL (Suitable for Operation with up to 100% Fresh Air) READ MANUAL CAREFULY BEFORE INSTALLING OR OPERATING THE FURNACE FOR YOUR SAFETY If you smell gas follow these instructions, 1) Open windows. 2) Do not touch electrical switches. 3) Extinguish any open flame. 4) Call the gas supplier immediately.
RECEIVING AND WAREHOUSING Inspect the unit upon arrival for any shipping damage. If any part is missing or damaged, notify the carrier at once. If the unit cannot be installed immediately, store it and its accessories in a clean and dry place. HANDLING AND SUSPENSION Do not handle the unit by attaching hooks, jacks or chains to the unit casing or any other component. Spreader bars are recommended when making single point lifts.
For service, it is advisable to maintain a minimum 24-inch clearance on the side opposite the controls and 42-inch clearance on the control side. If this unit is to be operated within a confined space or within a building of unusually tight construction, air for combustion and ventilation must be obtained from outdoors or other spaces freely communicating with the outdoors.
1) FOR POWER VENTED UNITS: The flue draft should be adjusted at the damper of the induced draft fan when the unit is operating on high fire. The overfire draft measured with a manometer at the test port in the relief door should be minus 0.01 to minus 0.50 in W.C. as specified on the rating plate of the unit. 2) FOR GRAVITY VENTED UNITS: The flue draft should be adjusted at the damper of the burner fan when the unit is operating at high fire.
*A tee shall be installed in the supply line at the same elevation as the gas inlet connection. The tee must be equipped with a nipple and pipe cap to serve as a condensate collector. *Test for tightness of gas connections after installation. GAS VENT High gas pressure regulator (if required), low pressure regulator, pilot pressure regulator, gas pressure switch (if supplied), and normally open vent valve (if supplied) must be vented outside of building for an indoor unit.
5. Lubricate (if necessary) the burner, induced draft fan and main fan motors. The specifications on the motors for grease and oil shall be adhered to. 6. Check heater outlets and exhauster, or induced draft discharge for obstructions. 7. Check fan-limit control.
5. Check supply fan motor load against rating plate figure. If actual figure is significantly different than the rating plate value, take corrective actions with respect to duct work and accessories external to the unit 6. The thermal overloads must be left set appropriate to the motor performance after all adjustments have been made. 7. Repeat steps 2 through 6 for the induced draft fan motor (power vented units only). 8. Remove jumper from fan switch if installed in step 4 above. 9.
The equipment has been electrically and fire tested prior to shipment. However, during transit, misadjustment of controls and loose wires could develop. Do not assume a control is defective until it and its associated wiring is checked. This equipment has may items supplied to us by outside vendors. This manual is accompanied by information sheets on most of these items which should be referred to for detailed service information.
6. UNABLE TO ADJUST FIRE TO BURN CLEANLY. A) B) C) D) E) 7. Insufficient exhauster* draft. Insufficient or too much fuel at supply. Incorrect adjustment of air shutters at burner. Insufficient combustion air available. Burner blower wheel running backwards. INSUFFICIENT HEAT BEING DISCHARGED INTO AREA. A) B) C) D) E) Main fan blowers running backwards. High limit switch setting too low or defective. Burner locked in low fire position. Ductstat setting improper or defective.
NOTE: Refer to manufacturer literature provided for maintenance requirements of optional equipment. BEARING INSTALLATION AND MAINTENANCE NOTE: To prevent premature failure – please ensure greasing instructions below are applied. As well, tighten bearing set screws, collars, and wheel lugs every four to six months.

TENSIONING V-BELT DRIVES 1. 2. 3. 4. 5. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions. Check tension frequently during the first 24-48 hours of operation. Over-tensioning shortens the belt and bearing life. Keep belts free from foreign material that may cause slip. Make V-drive inspection on a periodic basis. Tension when slipping. Never apply belt dressing as this will damage the belt and cause early failure. Check and tighten belt tension.

ECONOMITE 400-33 & F400-33 GAS BURNERS INITIAL START UP AND ADJUSTMENT CAUTION: Only qualified service personnel should attempt initial start-up. 1. Study these instructions, the wiring diagrams and flame safeguard instructions. Locate and identify all of the burner components. 2. Have on hand: CO and CO2 tester, stack thermometer, 0” to 30” W.C. gas pressure gauge, U-Tube manometer and DC volt meter. 3. Make the proper setting on all limit controls and set the operating control to call for heat. 4.
22. Make the final setting of the air shutter by checking the flue gases with an “Orsat” or other similar combustion testing instrument. There should be no carbon monoxide and the carbon dioxide content should be within limits prescribed by the local gas company. Make sure that the main air shutter is locked securely in place. 23. Recheck pilot to make sure that its operation has not deteriorated because of main shutter adjustment. If necessary, readjust pressure regulator. 24.

GP TYPE C FORCED DRAFT BURNER C-6.2 TO C-12.9 INITIAL START UP 1. Make sure burner power switch is off and manual main and pilot valves are closed. 2. Make proper settings on limit controls. 3. Have on hand CO and CO2 tester, stock thermometer, 0” to 30”W.C. gas pressure gauge, u- tube manometer and D.C. volt meter. 4. Turn on burner power switch momentarily to check blower rotation. 5.
BURNER SAFETY CHECK 1. Start and stop burner several times to ensure proper operation. 2. Check operation of combustion safeguard control by simulating a flame failure, making certain the burner locks out on safety within the proper time. 3. Check operation of the air flow switch, making certain fuel valve closes when the air flow diaphragm switch opens. 4. Bypass discharge controller and check to ensure high limit will shut down burner on temperature increase. If changed reset as per factory setting. 5.
