The 4N/L-51/62-24, 44N/L-5/6-24 Patio Heater
direct spark ignition, sequence is as follows :
13. SEQUENCE OF OPERATION - GASLITER MICRO 50N IGNITION CONTROL
1. 24 volts supplied to the DSI control initiates the 3 second pre-purge cycle.
2. After completing the 3 second pre-purge cycle the DSI control generates high voltage to the
Spark Igniter, and 24 volts to energize the Gas Valve.
3. The Burner will light and establish a steady flame.
4. Once the flame sensor determines there is a steady flame established, the spark igniter is
then de-energized.
5. If a flame is not established during the first 20 second Trial for Ignition (T.F.I.), the unit will
perform an inter-purge and T.F.I. If a flame is not established during this attempt, another in-
ter-purge and T.F.I. will be performed. If a
flame is not established during the final attempt,
the unit will enter the soft lockout mode. ) (The soft lockout mode is a 30 minute delay time
after which the unit will reset to try to ignite the gas again as in NORMAL OPERATION
6. If there is a loss of flame during the run mode, the unit will energize the spark within 0.8 sec-
onds and perform a T.F.I., without the gas valve being closed first, this is called Spark Resto-
ration. If a flame is not established during Spark Restoration the unit will repeat the process in
step number 5 (above).
7. If a flame is present with the Gas Valve de-energized the unit will enter a hard lockout mode.
If there is an internal fault detected within the control, this will also cause hard lockout. A
qualified gas service person is required to repair or replace defective components with parts
from the manufacturer.

8. Periodically clean the heater with a mild detergent solution and rinse with clear water, or use a
commercially available specialty cleaner. In particular keep the surface clean and clear at the
base of the burner where air is taken in for combustion.
A complete replacement parts list is on page 29. Replacement parts are available from a local dis-
tributor in your area. Contact information for the manufacturer is available inside the front cover of
