PROPER MAINTANANCE
•
Keep the area around the log set clean and clear of debris.
•
When logs develop soot, turn burner on for 15 minutes then lightly spray soot areas with water. Soot will then evaporate.
•
Periodically examine and clean the venting system. Once every year, a qualified agency or certified chimney sweep should
examine and clean the venting system of the solid fuel burning fireplace in which the log set is installed.
APPLIANCE BREAK-IN
During the 2-3 hour appliance break-in period, you may detect an odor from the appliance as the various water- based paints used
in the manufacture of this log set cure. This is normal and temporary situation that is not a cause for alarm. However, you may want
to provide extra ventilation to the room during this time.
To ensure proper curing of the logs:
1) Ignite a 2” flame and maintain it for 1/2 hour.
2) Burn the logs in consecutive 1/2 hour periods, raising the flame an additional 2” to full flame height for a total of three hours.
TROUBLE SHOOTING
Log Set is Smoking/Sooting Excessively
It is natural and unavoidable for vented log sets to produce moderate levels of carbon (soot) where flame contacts the logs. How-
ever, if soot is produced where there is no flame impingement, one of the following may be the cause;
Fireplace venting system not drafting properly: Make sure the damper is wide open at all times. Preheat the flue in very cold
weather by burning the log set at very low level, then slowly increasing the flame height over a matter of hours. Have the fireplace
and the venting system professionally cleaned.
Excessive flame impingement or blockage: Make sure there is proper spacing between the logs so they are not smothering the
flame. Rearrange the logs so they are touched less by the flames.
Excessive gas supply/pressure: Make sure the gas pressure coming into the fireplace does not exceed the maximum pressure
allowed with this gas set (refer to page 2). If you are using the gas logs with an “EASY” Safety Pilot Kit, make sure you installed the
correct orifice into the set.
Burner is Excessively Noisy
Please Note: The movement and combustion of gas will create low, unavoidable levels of noise.
Excessive gas pressure: Make sure the gas pressure coming into the fireplace does not exceed the maximum
pressure allowed with this gas set (refer to page 2). If you are using the gas logs with an “EASY” Safety Pilot Kit, make sure you
installed the correct orifice into the set.
Passage of air/gas across irregular surfaces: There may be burrs, paint or other blockages on the burner bar ports. Check
these ports and remove any blockage.
Gas Connector: Relieve any tight bends or kinks in the Flex Connector or switch to a smooth aluminum or copper connector, which
can be purchased at hardware or home improvement stores. Do not use Flex Connectors other than those supplied by Rasmussen.
Burner Flame is Too High (8-12” Above Top Logs) or Too Low (Below Top Logs)
Incorrect gas supply, pressure, or burner orifice used: Make sure the gas pressure coming into the fireplace falls between the
minimum and maximum pressures allowed with this gas set (refer to page 2). If you are using the gas logs with a safety pilot kit,
make sure you installed the correct orifice.
Blocked ports (low flame only): Free the main burner orifice and burner bar ports of any burrs, paint or other blockage.
SERVICE AND TROUBLESHOOTING GUIDE FOR MODELS USING THE “EASY” SAFETY PILOT KIT
Analysis and correction of control of service problems must be made by qualified gas service technicians only. Attempts to service
or repair the “EASY” Safety Pilot Kit by other than authorized service personnel will void the manufacture’s warranty. In general ,
failure of “EASY” Safety Pilot Control may be due to the reasons noted below:
1. Pilot will not light initially:
●
Check for loose Thermocouple terminal nut connection. Finger tip tighten plus 1/4 turn with wrench.
●
Check for improper pilot flame adjustment.
●
Check that Valve Knob is fully depressed during pilot lighting operation and held depressed for 30 to 60 seconds.
●
Check for defective Thermocouple.
●
Check for defective thermo magnet unit.
2. Pilot / Main burner clicks off after 5 to 30 minutes of burning:
●
Valve and Thermocouple are not defective, otherwise pilot would not initially light.
●
Thermocouple loses temperature difference between hot tip and cold junction (base).
●
Check that only tip of Thermocouple is in main burner flame.
●
Remove then replace logs to alter heat radiation pattern. Ensure that glass doors are open.
●
Ensure that proper size gas log set is installed. Too large of a set decreases cooling air flow.
