Don't be wowed by BTUs. The British Thermal Unit rating is an indication of the amount of heat a burner emits. Though more BTUs should generate higher temperatures, size and design also affect how hot a grill gets. We looked at cheaper models with BTU ratings as high as 45,000 that didn't grill as well as ones with lower ratings. So don't let a high number blind you to overall quality and user-friendly features. the number of BTUs increases, so does the amount of fuel that is used.

Series 1 & 2 natural gas lanterns use 3451 BTUs per hour; series 3 natural gas lanterns use 4854 BTUs per hour. Series 1 & 2 propane gas lanterns use 2800 BTUs per hour; series 3 propane gas lanterns use 4854 BTUs per hour.

British Thermal Units (BTUs) are the measurement of heat output. One BTU is the heat that will raise the temperature of one pound of water by one degree Fahrenheit. It is approximately the amount of heat generated by burning one blue-tip kitchen match. There are approximately 3.4 BTUs per watt per hour. High bulb temperature usually does not affect the life of the lamp unless the temperature is extreme.

Answer: BTU stands for British Thermal Unit, a measurement that represents heat output. Typically 10,000 BTU can heat approximately 500 square feet.

No, virtually no maintenance, other than periodically cleaning the glass, as you would wash your windows.

ANSWER: The lantern division of the R. E. Dietz Company moved to Hong Kong in 1956. In 1982 the factory was moved from Hong Kong into China. In 2005 the factory was again moved, and now operates in Jiangsu, China. The Dietz sales office still operates in Aberdeen, Hong Kong.

Most patients develop a tan or deepening of their normal skin pigmentation from PUVA therapy. The tanning may be uneven at first, with skin color lighter in areas affected by psoriasis. Some patients also develop freckles - particularly dark freckles - in areas affected by psoriasis.9 Burning from light treatment is a potential serious side effect of PUVA therapy. Regardless of how carefully light treatment is administered, some redness is likely to occur, especially at the beginning of therapy.

It is no longer legal to burn grass clippings because they cause too much smoke. This material must have been grown on the property it is burned on. You cannot move material from one location to another for burning.

The EnviroVent was designed for conventional pottery techniques. A large load of burn-out pieces may momentarily overload the EnviroVent. We recommend smaller loads of burn-out pieces.

The rule of thumb is this. Given a room with adequate insulation and typical ceilings (8 feet +/- 1 foot), each 10,000 Btu's of heat output from an efficient gas appliance will heat approximately 350 sq. ft. If the area to be heated has pitched or vaulted ceilings, poor insulation, or drastic air movement then the heating ability will be reduced. (Vented gas logs are not to be considered in this calculation as they are designed for appearance only.

SEALITE solar lanterns are designed to be extremely user-friendly, maintenance-free and offer years of reliable service. The solar modules convert sunlight to electrical current, which charges the battery. The battery provides power to operate the lantern at night. All lights use energy-efficient and durable Light Emitting Diodes (LEDs). LEDs consume about 90% less power than conventional light systems and will burn up to 100,000 hours.

Lanterns are rated based on light output. Usually stated in terms of "range" this is based on an internationally-accepted standard. Our lanterns are available in 1 mile, 2 mile, 3 mile, 5 mile, 6 mile, and 7 mile versions (larger available on request). Please check your local requirements to determine which lantern is required for your particular installation.

The range of applications for our solar products is limited only by the imagination of our customers, and their reliability and versatility have made them ideal for applications such as:

Yes, as long as you follow our directions and keep them away from flammable materials. The enclosed design protects the flame from coming in direct contact with other materials, and the handle keeps the lantern a safe distance below tent canopies when suspended in a tent. Be sure not to touch the heat shield when the lantern is burning, or until it has had sufficient time to cool after use. Never leave a burning candle unattended.

We have parts and make repairs to Butterfly, Egret Brand, Wenzel, Sea Anchor, American Camper, Petromax, Hipolito, Geniol, Aida, BriteLyt & other models of Pressurized lanterns. And (no labor cost) You pay for parts and shipping only. Note: May remove nickel, chrome from *older generation lanterns………test a spot on the lantern, before applying to larger area) “Blue Buster” is a registered to the prospective owner/inventor. (*Older generation.

These lanterns have a built in PIR (Passive Infra-Red) motion sensor. The way that PIR works is by detecting changes in temperature within the range of the sensor. (more) For additional information about how the PIR works go to howstuffworks.com.
