I got the dreaded E1 code the other day but thanks to the Englander site and this forums search box I was able to find the vacuum hose to the exhaust blower cracked and leaking air. I temporarily sniped the hose shorter and reconnected it after clearing out the fitting on the blower. Now my question for the permanent repair. My hose is white and I have seen some pictures of blue vacuum hoses, Which one is better and where can I get it ? Because my house is small I run the stove at 1 0. I think that this makes the stove hotter and thats why the hose failed after only 1 1/2 seasons of use. Is there any mods done to keep this from happening ?
