A propane heater hose that is too small for its length drops that pressure before it reaches the manifold.\u003c\/li\u003e\n  \u003cli\u003eOne hose carries propane or natural gas, so a Frost Fighter heater hose bought for a propane job runs the same heater off a natural gas meter next season.\u003c\/li\u003e\n  \u003cli\u003eThe 50 ft propane hose connects your LP gas tank to your heater from outside the enclosure. That keeps the tank the 6 ft (IDF) or 10 ft (IHS1500) Frost Fighter requires from the burner and clear of the discharge.\u003c\/li\u003e\n  \u003cli\u003eThree bores and two lengths cover the DF, IDF, IDH, and IHS LP\/NG models, so a rental fleet can carry the Frost Fighter hose for each heater it sends out.\u003c\/li\u003e\n  \u003cli\u003eFrost Fighter has built portable heaters in Winnipeg for 60 years, and the hose ships from Canadian stock, so a replacement never waits on US freight.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eChoose Your Size\u003c\/h2\u003e\n\u003cp\u003eEach \u003cstrong\u003eFrost Fighter LP\/NG hose\u003c\/strong\u003e ships as one bore and one length.

The 1-inch propane hose comes in both lengths; the Frost Fighter heater hose in 3\/4 in. remains the IDF supply.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"\u003e\n    \u003ch3 itemprop=\"name\"\u003eCan I use the same hose for natural gas and propane?\u003c\/h3\u003e\n    \u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\n      \u003cdiv itemprop=\"text\"\u003e\n        \u003cp\u003eYes. The Frost Fighter hose carries either fuel. Only the regulator train changes. As a natural gas hose for heater supply at 7 to 14 in. water column, it needs no regulator. On the heater, a red-handled ball valve switches the manifold between fuels.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"\u003e\n    \u003ch3 itemprop=\"name\"\u003eDoes it come as a propane heater hose with regulator?\u003c\/h3\u003e\n    \u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\n      \u003cdiv itemprop=\"text\"\u003e\n        \u003cp\u003eNo, the hose ships alone. Every Frost Fighter LP\/NG heater needs a secondary pounds-to-inches regulator, sold separately, and propane above 10 PSI needs a first stage. A propane tank to heater hose without that regulator cannot bring tank pressure down to the 14 in. water column the burner inlet accepts.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Frost Fighter","offers":[{"title":"3\/4\" x 25ft","offer_id":67728737534316,"sku":"47105A","price":358.75,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" x 50ft","offer_id":67728737567084,"sku":"47105","price":621.25,"currency_code":"CAD","in_stock":true},{"title":"1\" x 25ft","offer_id":67728737599852,"sku":"47107","price":796.25,"currency_code":"CAD","in_stock":true},{"title":"1-1\/4\" x 25ft","offer_id":67728737665388,"sku":"47106","price":1041.25,"currency_code":"CAD","in_stock":true},{"title":"1\" x 50ft","offer_id":67728737632620,"sku":"47107A","price":1058.75,"currency_code":"CAD","in_stock":true},{"title":"1-1\/4\" x 50ft","offer_id":67728737698156,"sku":"47106A","price":1811.25,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/5405\/files\/FrostFighterLP_NGHose.webp?v=1792161759","url":"https:\/\/cleanflow.net\/products\/frost-fighter-propane-natural-gas-hose","provider":"Cleanflow","version":"1.0","type":"link"}
