patio NPC05, Assembly Instructions Manual

 
At this point we need to stop assembling the heater and test for any possible gas leaks in the 
regulator assembly and head to feed line connection.  In order to achieve the leak testing we 
must attach the twelve-foot hose and couplers to the gas supply.  If you are not comfortable 
either hooking up the valve at the gas supply line or leak testing the unit you should contact a 
licensed plumber, gas technician, or public utility.

Step 8: 
 
1)  Since there are a variety of possible gas supply 

configurations our directions can only be 
general in nature.  

2)  First, shut off the flow of gas to the stub.   
3)  This can be accomplished at the stub if you 

have a shut off on your stub.  If not, you will need to shut off the gas at 
its source to your stub.   

Figure #8

4)  Attach the combination coupler/shut off valve onto your ½” gas line.  

Your line may be larger than ½” so it must be reduced to ½” in order to 
attach the shut-off valve.  This is a very safe and convenient system so 
please do not try to modify it in any way, 

5)  Use an approved pipe sealant or Teflon Gas tape to seal the connection 

from the stub to the shut-off valve. (See Figure #8) 

 
 
Step 9: 
 
1)  With gas still shut off.  Insert one of the 3/8” male nipple fittings at end 

of the 12 foot hose into the coupler at the end of the 
shut-off valve/coupler.   
 

Figure #9

2)  You can engage and disengage the couplers 
 

by just sliding the ring back at the end of the 

coupler.  The male nipple at the ends of the 

hose should insert and disengage easily.   
 

3)  The couplers can only work one way.  When 
 

the unit is not in use you can leave the hose 

attached to the heater or you disengage the 

hose set either at the heater or at the fuel  

supply or at both points. (See Figure #9) Please try to position the 

      hose so that it does not present a trip hazard.
