Description

This kit converts Amana gas-fired units from natural to propane gas. The conversion from natural gas (as shipped

from the factory) to propane gas requires:

- Replacing burner orifices

- Replacing pilot orifice (Package Gas-Electric Units only)

- Replacing gas valve regulator spring (all single stage units)

- Removing NOx screens/turbulators (screens/turbulators not used on all units)

- Applying conversion identification labels

Any conversion to propane gas is the responsibility of, and at the risk of, the person making the conversion. This kit

applies only to the following:

RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.

ATTENTION INSTALLING PERSONNEL

As a professional installer you have an obligation

to know the product better than the customer.

This includes all safety precautions and related

items.

Prior to actual installation, thoroughly familiarize

yourself with this Instruction Manual. Pay special

attention to all safety warnings. Often during

installation or repair it is possible to place

yourself in a position which is more hazardous

than when the unit is in operation.

Remember, it is your responsibility to install the

product safely and to know it well enough to be

able to instruct a customer in its safe use.

Safety is a matter of common sense...a matter of

thinking before acting. Most dealers have a list of

specific good safety practices...follow them.

The precautions listed in this Installation Manual

are intended as supplemental to existing

practices. However, if there is a direct conflict

between existing practices and the content of

this manual, the precautions listed here take

precedence.

General Information WARNING PERSONAL INJURY HAZARD This conversion kit must be installed by a qualified agency in accordance with the manufacturer’s instructions and all applicable codes and requirements of the authority having jurisdiction. If the information in these instructions is not followed exactly, a fire, explosion or production of carbon monoxide can result causing property damage, personal injury or loss of life.

Orifice Conversion The gas manifold along with the gas valve must be removed in order to access the burner orifices. Before proceeding, shut off gas supply at manual shutoff and turn off power to unit. 5. Remove the screws securing the manifold and valve to the burner bracket. Separate gas manifold and valve from burner bracket. ALL OTHER CONDENSING FURNACES 1. Disconnect wiring from the gas valve. 2. Where necessary, cut wire ties securing wiring to manifold. CAUTION 3.

Orifice Conversion 2. Replace with propane gas pilot orifice provided and reconnect wiring. Use care, do not damage igniter. Package Gas-Electric Cont’d PILOT ORIFICE REPLACEMENT PACKAGE GAS-ELECTRIC UNITS EQUIPPED WITH PILOT The pilot orifice must be replaced on Packaged Gas-Electric Units equipped with a Honeywell “Smartvalve” and pilot ignition system.

Gas Valve Regulator Spring Replacement SINGLE STAGE UNITS ONLY The gas valve regulator spring must be replaced on all single stage gas furnaces and packaged gas/electric units. Replace the gas valve regulator spring with the propane gas regulator spring from the proper spring kit. Follow the manufacturer’s instructions provided in the spring kit. Discard all unused spring kits. Two-stage units do not require a spring change. CAUTION Spring kits are not interchangeable.
PAGE 7
NOx Screen Removal WARNING PERSONAL INJURY HAZARD All metal screens must be removed from the heat exchanger tubes when using propane gas. Failure to comply could cause serious personal injury or death. Failure to comply with this requirement will also void warranty coverage. NOTE: To prevent premature heat exchanger failure, follow the instructions below to remove all metal screen inserts from the entrance of heat exchanger tubes during propane conversions. Not all models will have metal screen inserts.

Manifold Reinstallation Condensing & Non-Condensing Furnaces CAUTION 1. Reinstall gas manifold and valve. Pilot assembly must be properly aligned with burners for proper ignition. Refer to Figure 11. 2. Reconnect wiring (and burner box hose on GUD and GCD furnaces) to gas valve. Secure wiring to manifold using wire ties provided. Ensure wiring does not interfere with orifices or burners. Package Gas-Electric PACKAGE GAS-ELECTRIC UNITS EQUIPPED WITH PILOT CORRECT POSITION 1.

Adjustments, Checks, and Tests The following adjustments and checks are a required part of this conversion. Adjustments and checks include: • Leak checking orifices • Verifying proper igniter positioning • Checking line and adjusting manifold gas pressures • Verifying proper unit operation (input rate, operational sequence, burner flame, temperature rise, etc.

Using an Allen wrench, adjust low stage manifold regulator to the required pressure (Table 2). Ensure that the appropriate orifices have been installed and the manifold pressure has been set as stated in these instructions. 10. Reinstall the low stage manifold regulator cap screw. Confirm low stage manifold pressure. 11. Turn OFF gas supply to unit, and disconnect manometer.

Setting GUD/GCD Manifold Pressure Only small variations in gas flow should be made when adjusting the gas valve pressure regulator. For propane gas, the manifold pressure must 9.7 to 10.3” W.C. WARNING To prevent death or personal injury due to carbon monoxide, all hoses must be connected as shown in Figure 12. Failure to connect the hose between the pressure switch and the burner box could result in excessive generation of carbon monoxide.
