2. CONDENSATE REMOVAL SYSTEM

The Bobcat B-120 and B-200 boilers are equipped with a built-in condensation drain and trap. The trap must be filled with water. DO NOT operate the boiler without fill- ing the trap with water to prevent flue gas discharge into space. Periodic inspection should be made of this assembly for deterioration of the tubing and to insure that the trap is not plugged. If it is plugged or appears to have excessive sediment in it, it should be removed from the drain assembly, straightened out to clear the obstruction, reformed, filled with water and reinstalled as before. (See Figure 7).

Leave the top of the condensate drain tee open, to act as a vacuum breaker. Do not allow any part of the condensate removal system to be exposed to freezing temperatures, or any other conditions that could cause blockage.

If a neutralizing system is installed, the filter medium will require periodic changing, to ensure it’s effectiveness. Refer to the neutralizing unit’s manufacturers instruc- tions, if available, or change the medium on an annual basis.

3. PIPING INSPECTION

Look at all water piping. There should be no leaks or signs of leaks at any pipe joints or around the boiler.

4. SYSTEM WATER PRESSURE INSPECTION

The boiler water pressure is indicated on the pressure gage (See Figure 1 for location). The boiler water outlet temperature is normally indicated on the temperature display (See Figure 1 for location and Figure 9 for digits illustration). For most installations, it should indicate

about 12 to 15 psi pressure when temperature is about 70 to 100F and from 15 psi to 25 psi when temperature is up to 195˚F. FOR YOUR SYSTEM, there is one correct pressure for each temperature. ASK YOUR INSTALLER OR SERVICEPERSON TO EXPLAIN AND SHOW YOU. Learn what normal pressure to look for. If pressure increases from normal, the relief valve will open to relieve the pressure. Call your service organiza- tion if pressures are higher or lower than normal, and if the relief valve spills water. Repair or adjustment is needed.

5. UNUSUAL NOISE

Stand near the boiler and look and listen. As the burner start and shut off, there should be no unusual noise.

6. BOILER ROOM AIR SUPPLY

Ample boiler room fresh air is required for combustion (non-direct vent installation) and ventilation (direct-vent installation).

Check air vents for continues positive supply of air as required. Air needs are greatest in cold weather if boiler installation is non-direct vent method. Air vents must be open and free of obstruction.

Warning: The flow of combustion and ventilating air to the boiler should not be obstructed.

Warning: If you find any problem during your inspection, call for service immediately.
