Freeze Protection for a Heating Boiler System (if required)

1.Use only properly diluted inhibited glycol antifreeze designed for hydronic systems. Inhibited propylene glycol is recommended for systems where incidental contact with drinking water is possible.

￿WARNING: Do not use undiluted or automotive type antifreeze.

2.A solution of 50% antifreeze will provide maximum protection of approximately -30°F.

3.Follow the instructions from the antifreeze manufacturer. Quantity of antifreeze required is based on total system volume including expansion tank volume.

4.Glycol is denser than water and changes the viscosity of the system. The addition of glycol will decrease heat transfer and increase frictional loss in the boiler and related piping. A larger pump with more capacity (15% to 25% more) may be required to maintain desired flow rates and prevent a noise problem in a glycol system.

5.Local codes may require a back flow preventer or actual disconnect from city water supply when antifreeze is added to the system.

COMBUSTION AND VENTILATION AIR

Provisions for combustion and ventilation air must be in accordance with Section 5.3, Air for Combustion and Ventilation, of the latest edition of the National Fuel Gas Code, ANSI Z223.1, in Canada, the latest edition of CAN/CGA- B149 Installation Code for Gas Burning Appliances and Equipment, or applicable provisions of the local building codes.

Provide properly-sized openings to the equipment room to assure adequate combustion air and proper ventilation when the unit is installed with conventional venting or sidewall venting.

Check this filter every month and replace when it becomes dirty. The filter size is 12" x 16" x 1" (30.5cm x 40.6cm x 2.5cm) . You can find this commercially available filter at any home center or HVAC supply store.

Installing Combustion Air Filter

To install the filter(s), remove the combustion air inlet panel(s). The 985,000 - 1,435,000 Btu/hr models have one combustion air inlet panel located on the left front of the unit (see Figure 4). The 1,795,000 and 2,065,000 Btu/hr models have two combustion air inlet panels located on the left and right front of the unit (see Figure 5).

1.Loosen knurled knob at the bottom of the control panel cover.

2.Pull the bottom of the panel(s) out and down to remove.

3.Place filter(s) in opening(s).

4.Replace combustion air inlet panel(s).

Combustion Air Filter

The 985,000 - 2,065,00 Btu/hr models have a standard air filter(s) located behind the combustion air inlet panel(s). This filter helps ensure clean air is used for the combustion process.
