Long Temperature resistant silicone liner. Reinforced with multiple plies of polyester. Removal and Replacement To remove and replace the door hoses, use the following steps: 1) Turn off power to the air combustion blowers. 2) Ensure that the fire in the firebox is extinguished, which will allow the water to cool. 3) With hose clamps or vice-grips, pinch the door hoses in the middle of the hose. 4) Before removing the old door hose, cut the new pieces of door hose, one at 19 inches and the other at 21 inches. These measurements are critical. 5) Pinch the new door hose in the middle of the hose, creating a tight seal. 6) Loosen the hose clamps on each end of the door hose. 7) Remove the first end of the door hose needing replacement. 8) Push on the end of the new door hose and repeat the steps for the opposite end of the hose. 9) Tighten the hose clamps, securely fastening the door hose to the nipple on the furnace or firebox door. 10) Remove the vice-grips pinching the door hoses.
