Open Roads Forum  >  Tech Issues  > Permanent rubber hose for LPG inside RV? Reply to Topic  |  Subscribe  |  Print Topic  |  Post New Topic  |  Oldest first Newest first  Page of 2   Next beemerphile1 • View posts I'm only 57, I'm not yet a Senior Member Joined: 04/20/2007 View Profile Good Sam RV Club Member Online Posted: 02/08/12 09:04am Link  |  Quote  |  Print  |  Notify Moderator A fellow RVer tells me that they have a rubber connecting hose on the permanently installed furnace. Anyone else have this? Both of mine are hard piped with copper to the furnace gas valve. I know it would never meet muster in sticks/bricks installation. Does RVIA allow this? I'm not talking about a hose for a Wave or other heater but the permanently installed LPG furnace. It seems like a really bad idea to me to have a rubber hose snaking inside a cabinet where it will seldom be seen or inspected. What do you have?

There are a couple of rigs out now that use entirely non-metallic LP lines. -- Chris Bryant My RV Service Blog The RV.net Blog jauguston • View posts Bellingham, WA Senior Member Joined: 07/03/2005 View Profile Offline Posted: 02/08/12 09:24am Link  |  Quote  |  Print  |  Notify Moderator There is a specific hose made for high pressure propane. I have used it for my heaters for the last 7 years running from the coach tank to the front area on three different coaches. I trust the hose more than vibration crack susceptible copper.They use copper because it is cheaper.

The RVIA does not establish the building codes for RV's. They do however, require that their members comply with the applicable NFPA codes and other standards in order to get the RVIA label for a particular model. NFPA 58, the LP gas code, does not prohibit the use of appropriately rated hoses or plastic tubing for residential or vehicle use. Keep in mind, the LP distribution plumbing in an RV is operating at a very low pressure.

Like Dutch said, everything inside the coach is on the low pressure side of the regulator. * This post was edited 02/08/12 06:11pm by Corkey05 * 2008 HR Endeavor PDQ - Blazer 4 Down FMCA F374292 jauguston • View posts Bellingham, WA Senior Member Joined: 07/03/2005 View Profile Offline Posted: 02/08/12 10:27am Link  |  Quote  |  Print  |  Notify Moderator To add to what Dutch posted I on the other hand I am running tank pressure to my heater. The high pressure propane hose is rated for 300 psi and sees no more than 100 psi. The little green one pound tanks have the same pressure as the coach tank and all the plumbing in the heater before its regulator do too. The heaters are rated for safe use in enclosed inhabited spaces when the directions are followed regarding provision of fresh air. Fot that heater the requirement is a opening the equivelent of a 3" diameter hole. We satisfy that by slightly opening one of the roof vents. * This post was edited 02/08/12 12:41pm by jauguston * Ex-Tech • View posts West Senior Member Joined: 08/27/2011 View Profile Posted: 02/08/12 05:37pm Link  |  Quote  |  Print  |  Notify Moderator The corrogated "flex" copper should never be used in a RV. Never! These lines are not made to withstand constant vibration. I sell these where I work and wanted to use one when I installed my Wave heater so I called the manufacturer and they stated what I said above. dougrainer • View posts Carrolton, Texas Senior Member Joined: 06/11/2007 View Profile Offline Posted: 02/08/12 06:01pm Link  |  Quote  |  Print  |  Notify Moderator Remember, the Rubber hoses used in RV's AFTER the regulator are only handling LOW pressure. Rubber hoses are used in RV's for low pressure all the time especially in slide rooms that have LP appliances and other areas that you cannot run copper lines to. NEVER use anything but UL approved Rubber or hard copper lines, no flex metal lines at all.

Says that it's rated for LP and natural gas.
