You'll find several dealers of gas wall heaters listed in the Yellow Pages under "Appliances - Home Dealers and Service". Online use a search engine like Bing, Google or Yahoo or a contractor referral service. Some retailers who sell vent-free gas appliances offer installation service and so do some plumbers and gas company service mechanics. Ask the installer if he/she is qualified to do the electrical wiring, as well and be sure that all required inspections are completed before you make your final payment.
