Not that it matters, but I just had a similiar problem with an RLP35. It would stay on only as long as you held the pilot button in. Did all of the checks and ultimately found that the problem was debris, maybe a spider web in the fuel tube. The flame before cleaning was not big enough to reach the thermocouple. After cleaning, the thing just purred. They offer the same advice for BBQ's each season to make sure you clean out the fuel tubes. Hope it helps--I have an extra thermocouple now if someone wants to buy it!!!!!!!!!!
Heater will run as long as the control valve is pressed. According to DESA test these parts. NOTE: Not all heaters are equipped with A relay. Thermocouple Turn off gas supply. Remove thermocouple from gas valve. Using a digital multi-meter set to the lowest DC millivolt setting (meter needs to have alligator clips on ends of leads), clip black lead to the very tip of thermocouple (end removed from valve). Clip red lead to the outer casing of thermocouple for ground. Relight unit output should be between 18 and 28 millivolts. Relay Turn off gas supply. Remove bottom of base (if equipped). Relay is a normally open circuit between terminals 4 and 6 which closes when current is supplied. Using a digital multi-meter measure the resistance. With no power to unit, resistance between terminals 4 and 6 is open circuit or no resistance. Apply power to relay. Resistance between terminals 4 and 6 should be less than 100 mili ohms. www.reddyparts.com

Thermocouple
Turn off gas supply. Remove thermocouple
from gas valve. Using a digital
multi-meter set to the lowest DC millivolt
setting (meter needs to have alligator clips
on ends of leads), clip black lead to the
very tip of thermocouple (end removed
from valve). Clip red lead to the outer casing
of thermocouple for ground. Relight
unit output should be between 18 and 28
millivolts.
Relay
Turn off gas supply. Remove bottom of
base (if equipped). Relay is a normally
open circuit between terminals 4 and 6
which closes when current is supplied.
Using a digital multi-meter measure the
resistance. With no power to unit, resistance
between terminals 4 and 6 is open
circuit or no resistance. Apply power to
relay. Resistance between terminals 4 and
6 should be less than 100 mili ohms.
