You must provide at least a three square foot opening of fresh, outside air for each 100,000 BTU's of heat. This equation is listed in your owner's manual.

Keep portable heaters and space heaters at least three feet (one meter) away from anything that can burn. Keep children and pets away from heaters, and never leave heaters on when you leave home or go to bed.

There are four controls for the cabin heating system. One is the little red-knobbed handle on the floor just aft of the gearshift lever. The others are the three sliders, two black-knobbed and one red, on the dash. The top black knob controls how much fresh air is coming in. It goes from off (left) to full flow (middle) and then turns the cool air fan (up front, behind the gas tank) on low (I), med (II), or high (III) speed. The second knob controls where the cool air goes.

None of the forced air heaters can be used without electricity. The fan on the heaters requires 110 volts AC electrical current to operate.

You may use kerosene, number one fuel oil, or diesel fuel. You will notice an increase in odor when using diesel fuel. You will need to perform more frequent maintenance of the spark plug and filters. You may need to use an additive when the temperature gets below freezing to keep the fuel from congealing. This could be caused by low fuel supply, incorrect inlet pressure, bent fan blades, damaged or defective sail switch or fuel valve, or if the tank valve is not completely open.

Use enough repellent to cover exposed skin or clothing. Don't apply repellent to skin that is under clothing. Heavy application is not necessary to achieve protection. Do not apply aerosol or pump products directly to your face. Spray your hands and then rub them carefully over the face, avoiding eyes and mouth.

Yes, the air purifier kills germs and bacteria and destroys odors; but it does not dispose of the particulate, which is airborne. This requires a quality particulate filter.

Yes and no. Outdoor models are designed for well ventilated places. Well ventilated does not mean you have a bit of a draft under a crack in the door. In a garage with a window or garage door open, yes you can safely use any of the 12-IR -> 24-IR range of heaters The DESA range of infra-red heaters is the way to go for indoor infra-red heat. These units are designed for indoor use and have safety mechanisms built in to protect you.

The fresh water supply pipes that need protection from freezing are those that are exposed below the floor of an RV or along an outside wall where the heat loss is greatest. Typically the section of ½" (1.3 cm) dia. fresh water supply pipe that is most susceptible to freezing usually is the section running from the fresh water holding tank below the floor for some distance then goes up through the floor to the water pump. To protect a section of ½" (1.

NO! The kerosene, propane, or natural gas construction heaters may not be used for home heating, even temporarily. This heater is designed to operate on a construction site or similarly open environment. The heater can be used in semi-closed buildings if the proper amount of fresh air is provided per the instructions for ventilation air in the owner's manual.

How does the In-Line Scale Eliminator Cartridge work? [Difference between "filter" and "conditioner."]

Most water heaters are only in service for 2-3 hours per day and they often have enough capacity to do extra work. If the BTU heating output of the water heater is equal to or greater than the heating load, you can probably use it to heat as well. Look at the label on the heater for the BTU output.

Absolutely. We are careful to monitor the expiration dates of products and if anything does not have a lengthy freshness time once it gets to our customers, we will remove the item from the shelves of our warehouse and obtain fresh product.

Since all wood stoves require oxygen for the combustion process, the oxygen most often is obtained from within your home. A fresh air kit brings cold air from outside your home to the air intake. Doing so assures that enough fresh air is available for efficient combustion. It also means you are not burning the air you already warmed.

This will depend on how air tight the room may be. If the room is very air tight it can form a negative pressure in the room and interfere with the proper functioning of the stove. If the unit is installed in a manufactured home, the fresh air kit is required.

Many of today’s highly energy efficient homes are very ‘tight’, and consequentially, it may be desirous to have supplemental fresh air brought into the building with advanced technology heat recovery systems (HRC). These systems actually recover much of the ‘heat’ present in the exhaust air and add that ‘heat’ to the fresh air being brought into the building. In this way, the air circulation system helps improve the overall heating efficiency of the system.

To calculate the minimum quantity of fresh air required in CFM (cubic feet per minute), calculate 10 cfm for each room (ex.: living room, bedroom, kitchen), 20 cfm for the master bedroom and 20 cfm for an unfinished basement. You can also consult an HVAC specialist to properly size your building.

This iceberg is just going to melt, and go into the ocean, anyway, so we should use it by covering it in insulating bubble wrap, towing it up the Mississippi river, and using it for irrigation water in the Midwest, which needs some water this year.

Yes part # 67FAK. This allows combustion air to enter the firepot from outside. This will increase the efficiency and reduce the likelihood of creating negative pressure or vacuum effect in your home.
