Marshall Excelsior ME806-16 Flo-Max Safety Notice
This product safety notice addresses field inquiries regarding the potential for frosting of the valve seal during operation in sub-zero temperatures. Click here for this safety notice.

Algas-SDI Vaporizer Safety
In order to safely service and work on a vaporizer, it is important to properly purge the unit of any propane (liquid and vapor). Algas-SDI has created a step by step procedure to help ensure your safety. Click here for this procedure.

Algas-SDI Direct Fired Vaporizer Bulletin
In 2002, Algas-SDI implemented a design change on the Algas style direct fired vaporizers.  As part of the engineering of this change, the burners now require a different operating pressure depending on the model.  The following Engineering Bulletin provides the details on the pressure requirements and procedure for setting the proper burner pressure.  Click here for this bulletin.

Updated 04/04/07 MAJESTIC/VERMONT CASTINGS SOLUTION FOR HARD-TO-LIGHT HONEYWELL GAS VALVES. HONEYWELL MILLIVOLT VALVE REPAIR KIT TECHNICAL BULLETIN #55

We have released several repair kits (RP Kits) for replacing Honeywell Valves 10001782 (natural gas) and 10001759 (propane) on various Majestic and Vermont Castings Gas Units. These kits all include the appropriate fuel SIT Valve with all brackets, hardware and piezo igniter parts needed to do a complete replacement of the Honeywell millivolt valve. See the list below.

VENT FREE GAS PRODUCTS - PILOT TROUBLESHOOTING TIP
Provided by Rassmussen Fireplace Log Company

Symptoms:
a) Unable or difficult to establish the pilot light; or
b) Burner(s) and/or pilot shuts down after a few minutes of operation.

Probable Cause:
The ODS Pilot has two small holes that draw in air to mix with the gas to create a stable pilot flame. Unfortunately, over time lint and dust in the air accumulate inside these holes, which disrupt the proper operation of the pilot flame.

Action to Take:
1) Gather tools needed: A vacuum cleaner with brush attachment. A can of compressed air with a tube (the type that is used to clean computer keyboards) or a drinking straw.
2) Vacuum up all lint, dust & debris from logs, grate, burner(s), burner air intake, and air shutter regions (underneath burner, where air gets drawn in), and pilot area.
3) Using the compressed air or a straw, blow out burner ports (where the main flame comes from), burner air intake and air shutter regions (end of burner(s) where gas and air mix), around the valve knob (the one you depress to light the pilot), and MOST IMPORTANTLY, the air intake holes of the ODS Assembly. These small air intake holes are between 1/16" and 1/8" in diameter and are located about 2" from the end of the pilot from where the pilot flame originates. Use the compressed air or straw to blow out these holes.

JURISDICTIONAL ACCOUNT RESOURCE
Jurisdictional accounts are those where more than one customer receive fuel from a single source in a public place. These include schools, churches and commmercial buildings. Another application is a situation where ten or more customers draw from a single tank or tanks manifolded together. The U.S. Department of Transportation (DOT) has published regulations that you will find necessary to know. Click here to access the full information.

VAPORIZATION "RULE OF THUMB" FOR ASME TANKS
Source: Sherwood LPG Products Liquified Petroleum Gas Control Technician's Guide The vaporization rate is a factor of (1) the temperature of the liquid and (2) the "wetted surface" area of the container. This applies to bulk installations equally as well as it does to cylinder systems.

In estimating the size tank required for any given load, it is necessary to decide on an average, or point at which the gas supplier will refill the tank. Of course, our minimum vaporation rate will occur when the liquid level is the lowest. On the assumption that the tank will be refilled when the liguid level drops to 1/3 the fuel capacity of the tank, the following table will give you a good "rule of thumb" guide for various temperatures.



NOTE: The physical dimensions of the tank actually affect its vaporization rate. A small diameter, long tank makes a better vaporizing tank than a large diameter, short tank of equal gallonage. This is due to more square inches of surface area in the tank of smaller diameter. A sphere would have the minimum number of square inches of surface area per gallon of fuel, and consequently, the poorest vaporization factor. Thus the above table represents a conservative figure, recognizing that there will be some variation in vaporizing rates due to the physical differences in tanks of same gallonage.

Here is an example of how to use this "rule of thumb" for your bulk tanks: Suppose we had a tank 40" in diameter and 105" long and our worst winter temperature was 0 degrees F. The tank rarely drops below the 1/3 full mark. Would this tank under these circumstances, supply a continuous load of 350,000 BTU's an hour?

The "rule of thumb" would tell us that it would supply this load requirement 40" (D) X 105" (U) X 90 (taken from the table above, opposite 0 degrees F) = 378,000 BTU's.

Don't blame regulators for improper operation if the systems are operated with insufficient fuel storage. Regardless of the size of a regulator, it can't make pressure.
