Big Buddy hose clarifaction

[Jeremy airjer W]

I just hung up the phone after talking to tech support at Mr. Heater about the different hoses available for this heater.

According to Mr. Heater the hose with the quick connect fitting is the ideal hose for this unit. This is considered a low pressure hose because the propane is regulated before the hose. This means that the hose is never under pressure which can cause the oils/contaminates to squeeze out of the hose and contaminate the heater. This is why the filter is not needed if you are using this hose.

This hose is available with and without the regulator. If you are using it with a portable propane tank you will need the hose with the regulator. The hose without the regulator is intended for use with an already regulated propane supply that you would find on an R.V. hence the R.V. quick connect.

The other hose option is the one with the one pound thread fitting. This hose threads to the same fitting as the one pound cylinder would. The propane is regulated by the internal regulator of the heater. Because this hose is run directly from the tank to the heater it is considered a high pressure hose. Because of the high pressure oil/contaminates can be squeezed out of the hose. This is why it is strongly recommended to use the filter.

I was wrong in posting that the quick connect setup is better in the cold weather. It makes no difference which hose you use in the cold. I apologize for any confusion I may have cause regarding this aspect of hose function!

The quick connect hose;

- is ideal according to Mr. Heater

- has to be externally regulated (there is no internal regulator for this fitting) A regulator needs to be between the portable tank and the hose

- Because the Quick connect hose is a low pressure hose it requires no filter.

The hose that screws into the one pound fitting

- is a high pressure hose

- is internally regulated by the heater and requires no external regulator.

- the filter is recommended with this hose because the high pressure can "squeeze" contaminates out of the hose

I hope this helps clarify the two options a little better.

I'm having a huge problem with the quick connect hose. I'm not able to get the heater restarted after I turn it off once after using the hose. I'm getting spark but doesn't look like I'm getting gas. I know the hose is connected with gas in it. I guess I need to try to take it apart again and see what else I can find. I'm running out of ideas.

Hold in the knob like you are going to start it but pause just before the spark. Hold for 60 seconds before sparking.

I think with the low pressure hose it takes longer to work the air out of it after connecting/disconnecting it.

I have switched back to using the high pressure hose and filter setup. Quicker starts it seems like. I haven't had any issues running either hose setup except for the slower starts with the quick connect hose. Going on ... must be 5 years I think?

I put 1 lbs back one and I'mm still having issues. Maybe I pickup the other hose and filter and try that or I need a new thermocouple.

The thermocouple doesn't apply to starting the unit. It only comes into play after th pilot flames lit and then the thermocouple takes over and allows propane to flow through the unit.
