Get the installer's status first
Ask whether installation is complete, inspections or corrections remain outstanding, and the appliance has been commissioned. A builder leaving a key does not answer those questions. Locate the correct owner's manual and its first-use instructions. Heat & Glo describes curing of manufacturing finishes for some new appliances. Follow the specific model instructions and installer guidance rather than a schedule copied from a different unit.
Choose who will be there
Ask the installer who should supervise first-use directions, what room preparation is required, and whether a later cleaning or return visit is specified. Preserve working alarms and required ventilation. Schedule the task when a responsible person can attend, not while a guest is sleeping or the manager is leaving. Do not remove gas-fireplace glass or undertake service work to solve a first-use question yourself.
Record what actually happened
Keep a dated note of the completed steps and any outstanding item. If the owner smells gas, the safe action is to leave and call the gas supplier or emergency services from outside. Do not attribute an unexplained persistent smell or a gas odor to normal curing. A first-use explanation applies to the identified new appliance and documented instructions, not to every odor after a vacant season.
