IMPORTANT

READ ALL OF THE FOLLOWING WARNINGS AND

STATEMENTS BEFORE READING THE

INSTALLATION INSTRUCTIONS

WARNING

LIQUEFIED PETROLEUM (L.P.)

PROPANE GAS-FIRED BOILERS

Installation location ONLY as permitted in paragraph enti-

tled "LIQUEFIED PETROLEUM (L.P.) PROPANE GAS-

FIRED BOILER LOCATION" on page 4 of this instruction

book. The above warning does not apply to NATURAL

gas-fired boilers.

The installation must conform to the requirements of the

authority having jurisdiction or, in the absence of such

requirements, to the National Fuel Gas Code, ANSI Z223.1-

latest edition. The installation must also conform to the

additional requirements in this Slant/Fin Instruction Book

In addition, where required by the authority having jurisdic-

tion, the installation must conform to American Society of

Mechanical Engineers Safety Code for Controls and Safety

Devices for Automatically Fired Boilers, No. CSD-1. If there

is any conflict in the above requirements, then the more

stringent requirement will apply.

This manual must be left with owner and should be hung

on or adjacent to the boiler for reference.

WARNING

This boiler, gas piping and accessories must be installed,

connected, serviced and repaired by a trained, experienced

service technician, familiar with all precautions required for

gas-fired equipment and licensed otherwise qualified, in

compliance with the authority having jurisdiction.

WARNING LIQUEFIED PETROLEUM (L.P.) PROPANE GAS-FIRED BOILER LOCATION REQUIRES SPECIAL ATTENTION Liquefied Petroleum (L.P.) propane gas is heavier than air. Therefore, propane boilers, piping, valves should not be installed in locations where propane leaking from defective equipment and piping will “pool” in a basement or other space below the leak. A spark or flame from the boiler or other source may ignite the accumulated propane gas causing an explosion or fire.
PAGE 5
Sentry D. Vent or breeching into chimney should not be inserted past the inside wall of the chimney liner. E. All venting means should be inspected frequently. See Care and Maintenance and separate User's Information Manual. VENT DAMPER INSTALLATION The vent damper referred to in the following instructions is the Slant/Fin Corporation vent damper. This device is design certified by A.G.A. for use ONLY on specific Slant/Fin Corp. gas boiler models.
PAGE 6
Sentry GAS PIPING— A. Local installation codes apply. The pipe joint compound used on threads must be resistant to the action of liquefied petroleum gases. B. The gas supply line to the boiler should be run directly from the meter for natural gas or from the fuel tank for L.P. propane gas. See page 2 for location of union and manual main shutoff valve that may be specified locally. Selecting pipe size for natural gas: 1. Measure or estimate the length of piping from the meter to the installation site.

Sentry BOILER ROOM AIR SUPPLY AND VENTILATION An ample supply of air is required to obtain combustion and ventilation. ALL AIR COMES FROM OUTSIDE, directly through wall openings to the boiler or through unsealed openings around windows, doors, etc. in the whole building. When buildings are insulated, caulked and weather stripped, now or later on, direct openings to outside may be required and should be provided.

Sentry SAFETY INFORMATION FOR YOUR SAFETY READ BEFORE OPERATING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance is equipped with an ignition device which automatically lights the pilot. DO NOT try to light the pilot by hand. B. BEFORE OPERATING smell all around the appliance area for gas.
PAGE 15
Sentry a. Boiler (burner) is overfiring. CAUTION! National Fuel Gas Code ANSI Z223.1-latest edition, does NOT permit firing at a higher input rate than the input rate indicated on the boiler rating plate in order to avoid hazardous conditions such as explosion or carbon monoxide poisoning. b. Poor higher* heating value of gas is causing the actual input to be substantially lower than the rating plate indication. * “Higher heating value” of gas is commonly known as a “heating value.” 2.

Sentry 3. Water lines: slightest leaks should be corrected. 4. Low water cutoff, for operation (see instructions furnished with unit). 2. WATER LEVEL CHECK DURING HEATING SEASON A. Check water pressure regularly and add water slowly to system when needed. If much water is added, venting may be necessary. B. Regular loss of water from water boiler system may indicate either a system leak, or a faulty air control system, or a faulty automatic fill valve. 3. ANNUAL INSPECTION AND CLEANING A.

Sentry GENERAL TROUBLESHOOTING GUIDE FOR SERVICEPEOPLE BURNERS FAIL TO OPERATE CAUSE 1. Safety pilot out, or flame too low. 2. Gas supply valve shut off. 3. Electric switch open. 4. Blown or defective line fuse. 5. Operating or limit control contacts open or dirty. 6. Defective gas valve or pressure regulator; or plugged bleed line. 7. Obstruction at main burner orifice. 8. Break in wiring or loose contact at control terminals. 9. Improper wiring. 10. Improper controls. 11.

Sentry PIPING A HEATING - COOLING SYSTEM TO A WATER BOILER AND CHILLER The chiller must be piped in parallel with the boiler. Figure below illustrates a method of piping a heating-cooling system to a water boiler and a chiller. Hand valves (shown) or automatic valves must be installed to prevent circulation of chilled water in the boiler or hot water in the chiller. The air control system and pressure control system must operate with chiller only, or the boiler only, being valved to the piping system.

Sentry APPENDIX A Removal of Existing Boiler from Common Vent System "At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation." (a) Seal any unused openings in the common venting system.
