Lighting Instructions 

Before turning on the natural gas fuel supply, visually inspect the hose assembly for evidence of excessive 
abrasion, cuts, cracking, animal damage, or unusual wear and tear. If the hose leaks do not attempt to use the 
heater, replace the hose immediately.  Only use replacement hoses and other parts as specified by 

Patio 

Comfort

. 

Before Lighting 

 
If attempting to relight a hot heater, always wait at least five minutes.  The main heater components such as 
the emitter grid, gas hook up, and pilot assembly should be checked at least every two years by a qualified 
service technician or immediately if you feel the appliance is not working properly. 
 

To Light Heater  

1)  Be sure the control knob on the heater head is in the 

“OFF” 

position. 

 
2)  Turn the shut off valve at the house connection in a 

counter-clockwise

 direction to open. Be sure the 

quick connect couplers at the heater post and end of the hose at the shut-off are fully engaged and tight. If 
the couplers are not properly engaged, no gas will flow to the heater. 

 
3)  Gently depress the control knob on the control panel and rotate it counter clockwise to the “PILOT” 

position. 

4) 

This is very important

!

   Gently depress the control knob and hold the control knob to begin the 

flow of gas to the burner pilot assembly.  Depress the control knob in the “PILOT” position for up to 

2 

minutes on  new installations or reconnected hoses.   

This is how long it might take for the air to be 

purged from the hoses and feedline delivery system.  It will take less than 10 seconds for regular relighting.  

Do NOT continually press on the igniter while you are purging the line. 

This will only cause premature 

wear and tear on the ignition and weaken the charge created by the piezo ignition.  Occasionally depress 
the igniter and  you will hear when the pilot light ignites.. You can also see the pilot light through the pilot 
access port that has a small rectangular cover at the base of the heater head.  This is essentially the same 
safety system that you have on your water heater. Please be patient with this process. You can also hear 
the pilot light when it lights. 

 
5)  Once the pilot is lit, continue to depress the control valve for about 20 seconds or until the pilot flame     

remains lit after the control knob is released. 

 
6)  The burner may now be turned on to the full 

“ON”

 position for maximum heat output or it may be turned 

back to the “PILOT” position to reduce heat output and fuel consumption.  If you turn the control knob all 
the way back to the “PILOT” position, the main burner will go off and the pilot flame will remain lit. You can 
now re-ignite the main burner directly from the “PILOT” position.  On the first use, a little smoke is to be 
expected.  This is machining oils being burned off. 
 
 

The heater is designed to be operated in the full “ON” position only. 
Turning the heater down will result in incomplete combustion and 
sooting of the burner and very low heat output.  You can immediately 
re-light the main burner when the standing pilot is on.
