Adjustment, Start & Stop; Adjustment Procedure; Step 1: Reset The System - Eclipse RatioMatic RM Series Installation Manual

Adjustment, Start &
Stop
In this chapter, you will find instructions on how to adjust,
start, and stop the burner system. Become familiar with
burner control methods before attempting to make
adjustments.
■ The RatioMatic burners, described herein, are
designed to mix fuel with air and burn the resulting
mixture. All fuel burning devices are capable of
producing fires and explosions if improperly
applied, installed,
maintained.
■ Do not bypass any safety features. This can cause
fires and explosions.
■ Never try to light a burner if it shows signs of
damage or malfunction.

Adjustment Procedure

If you are adjusting the burner system for the first time,
then you must follow these steps:

Step 1: Reset the System

1. Set the low gas pressure switch to 20% below the
"Main Gas Inlet Pressure" range as specified in the
appropriate datasheet.
2. Set the high gas pressure switch to 20% above the
"Main Gas Inlet Pressure" range as specified in the
appropriate datasheet.
3. Close all the burner gas valves, manual and
automatic.
4. Try to ignite the burner; be sure the flame monitoring
system indicates a flame failure.
5. Activate the pressure switches and other limit
interlocks. Be sure the switches fail as intended in the
event of a power failure.
■ If simulated limits or simulated flame failure do not
shut down the fuel system within the required
failure response time, immediately correct the
problem before proceeding.

6. If the burner is firing into a duct or chamber with a
circulating fan, start the fan to produce a full process
air flow past the burner.
7. Adjust main gas inlet pressure to the ratio regulator
within the range specified in the appropriate
datasheet.
■ Gas inlet pressures must stay within the specified
range. Pressure above the specified range can
or
damage the ratio regulator.
■ Pressure below the specified range can impair the
ability of the ratio regulator to control the gas flow.
■ Operating the system outside the specified range
can cause excess fuel consumption and the
possible accumulation of unburned fuel in the
chamber. In extreme cases, this accumulation of
unburned fuel may cause fires or explosions.
8. Verify that the actuator opens the air BV towards the
back of the burner as shown in Figure 4.1. If it doesn't,
refer to the actuator's literature for instructions on how
to reverse the direction.
