I have a heater similar to this. Can the thermostat be changed to an electric?
By Collin C. - NFI Master Hearth Professional on October 22, 2013
Answer:Unfortunately, no. Hydraulic thermostat controls are a system that are integral to the design of the gas valve. The entire valve would have to be swapped with a millivolt version, which would also warrant the conversion of several other components. I apologize that a separate thermostat cannot be used.

How many square feet does this heat and is it efficient? What is the efficiency rating? We are looking for something to heat a 14 x 70 mobile home.
By eFireplaceStore on September 18, 2014
This unit is fairly efficient for a natural vent heater and is rated to heat approximately 700 square feet. However, that will not be sufficient for the size of your home. I recommend using the Empire RH50CB Closed Front Gas Room Heater with Blower - Propane
. This model will not only heat the entire area, but includes a blower to initiate circulation.

How do I light this?
By Tyler M. - NFI Certified Specialist on September 3, 2013
Lighting this gas heater is simple due to its piezo ignitor, which allows you to light the pilot without a match. Please see page 9 of the owner's manual
for the full lighting instructions.

If venting horizontally through wall how long must the vertical run be to end the venting?
By Collin C. - NFI Master Hearth Professional on April 1, 2014
Answer:The vent piping must conform to the 10/3/2 rule for this appliance. As such, the piping must extend 3 feet beyond the eave of the roof line. It must also have a 10 foot circle around the pipe termination of no obstruction, such as trees or another portion of the roof. If there is an obstruction, the pipe must be raised until a 10 foot circle of clearance can be achieved. You must then add 2 additional feet before terminating the vent.

According to the owners manual the flame on the pilot light should be 1/4 inch. It's at least 1 1/2 inches long. Is there a way to adjust the pilot light flame?
By Collin C. - NFI Master Hearth Professional on August 1, 2013
Answer:To adjust the pilot flame length, there is a brass screw that must be turned using a flat head screwdriver. The brass screw can be located immediately to the side of the main control knob used to light the pilot.
Please keep in mind that the pilot flame must extend past the thermocouple 1/4". The thermocouple is positioned away from the pilot hood, so the flame will be longer overall.

I have a Empire #RH-35-6 LP I was wondering if there was a conversion kit to make it ready for natural gas. And what does it consist of?
By Collin C. - NFI Master Hearth Professional on January 8, 2013
Answer:After checking with the manufacturer, I have found that there is a conversion kit for this unit. It consists of replacement pilot and main burner orifices, as well as a different air adjustment shutter and vent. The item is a special order and would take approximately 10 business days to ship.

I would like to vent through wall. I have 3 foot horizontal through dead air space than out wall. Can I do an angled up and put a wall weather cap on outside?
By Collin C. - NFI Master Hearth Professional on May 29, 2013
Answer:The RH35 can indeed be vented horizontally through a wall, however it must be terminated vertically. Horizontal terminations are only permitted with Empire's direct vent heaters.

Do you sell a programmable digital thermostat that would work with this unit?
By Tyler M. - Fireplace Specialist on December 10, 2012
Answer:Unfortunately, no. This heater has a built-in hydraulic thermostat.

I have an Empire RH-35-6 propane heating unit. It has started shutting itself down completely and seemingly
without any reason I can discern, including the pilot light.
I'm using it to heat a small greenhouse, so this problem is very inconvenient.
By Collin C. - NFI Master Hearth Professional on March 13, 2013
Answer:If both the burner and pilot flame is shutting down, the issue is most likely attributed to the thermocouple. Thermocouples can fail as early as 2 years and are a commonly replaced component. Before considering replacing the component, I would first check the positioning of the thermocouple to ensure that the upper third of the probe is engulfed in flame when the pilot is burning. The probe can also be cleaned with a piece of fine grit sandpaper. If this does not solve the problem, replacement will be needed.
