secured in place (S ee Installation Instructions), that vent term ina tes to the
atm osphere, and that vent tubes overlap properly (S ee Installing V ent Assem bly).
2. Inspect cham ber and venting to assure that these com ponents are physically
s o und, without holes or excessive corrosion and that the installation and/o r
reinstallation is in accordance w ith Suburban's Installation Instructions. (R eference
