AquaStar 170 VP manual Locating Your Heater For Safe Proper Combustion

LOCATING YOUR HEATER FOR SAFE PROPER COMBUSTION

Carefully select the location of your new heater. For your safety and for proper heater operation, you must provide an abundant supply of combustion air and install a proper vent. The heater may still operate even when improperly installed. However, an improper installation will be less efficient and may damage the heater. Improper installation can even result in human sickness or death due to oxygen deprivation and carbon monoxide poisoning. Follow the guidelines below:

1.You must not install this appliance in bath- rooms, bedrooms, closets or any occupied rooms normally kept closed.

2.Simultaneous operation of appliances such as exhaust fans, ventilation systems, clothes dryers, fireplaces or wood stoves may create a vacuum effect in your home. This can cause dangerous combustion by-products to spill back into your home rather than venting to the out- side through the flue.

3.A simple test for proper ventilation is to inroduce smoke (as from a candle) near the opening on the front of the heater. Have all appliances mentioned in the above paragraph operating at the same time. Have all doors and windows to the outside shut. If the heater does not suck the smoke into the opening while the heater is operating, you need to supply addi- tional combustion air to the heater and/or im- prove the vent system.

4.Observe the following instructions concern- ing additional combustion air.

Appliances located in unconfined spaces:

a)An unconfined space is one in which the volume is greater than 50 cubic feet per 1000 Btu per hour of the combined rating of all appliances installed in the space. That would be 8250 cubic feet for the AquaStar 170 alone.

b)In unconfined spaces in buildings of conventional frame, masonry, or metal construction, infiltration is normally ad- equate to provide air for combustion, ventilation, and dilution of flue gasses.

Appliances located in confined spaces:

The confined space shall be provided with two permanent openings, one com- mencing within 12 inches of the top and one commencing within 12 inches of the bottom of the enclosure. Each opening shall have a minimum free area of one square inch per:

-1,000 Btu/hr if all air is taken from inside the building.

-2,000 Btu/hr if all air is taken from the outside by horizontal ducts.

-4,000 Btu/hr if all air is taken from the outside by direct openings or vertical ducts.

Louvers, grills and screens have a block- ing effect. If the effective free area is not known, assume 20% to 25% for wood lou- vers and 60% to 75% for metal louvers.

Refer to the National Fuel Gas Code for complete information. In buildings of tight construction, all air should be taken from outside.

5.Place your heater as close to a vent or chimney as possible. Your hot water lines should be kept short to save energy. It is always best to have hot water lines insulated.

6.Having a floor drain or sink nearby is handy in case you need to drain water from your heater.

7.Place the heater in a location where water leaks will do NO DAMAGE to adjacent areas or lower floors. CONTROLLED ENERGY CORP IS NOT RESPONSIBLE FOR WATER DAM- AGE.
